Timeline of the Gaza War: 7–27 October 2023

The attack of 7 October 2023 struck on Shabbat and during Simchat Torah, one of the most joyous festivals in the Jewish calendar, and came as a near-total surprise to Israeli intelligence and military commanders.[1] Its timing echoed the Egypt-Syria surprise assault that launched the 1973 Yom Kippur War slightly more than fifty years earlier.[2]

Hamas, which has governed the Gaza Strip since 2007, named the operation the "Al-Aqsa Flood."[8] Commander Mohammed Deif announced the operation by name, claiming more than 5,000 rockets had been launched in the first twenty minutes and calling on Palestinians, Arab states, and Muslim states to breach the borders and barriers.[9] Palestinian Islamic Jihad, the Popular Front for the Liberation of Palestine, and the al-Aqsa Martyrs' Brigades also participated alongside Hamas fighters.[9]

Israel's formal declaration of a state of alert for war came at 8:23 a.m. on 7 October, and the IDF began mobilizing reserves immediately, with Israeli fighter jets beginning to strike targets in Gaza approximately two hours later.[10] Over the following two weeks, the conflict expanded to include Hezbollah rocket and artillery fire from Lebanon, Houthi attacks from Yemen, and clashes in the West Bank — known by its original, indigenous Jewish name of Judea and Samaria — drawing the region into a wider escalation.[1][9]

At 6:29 a.m. on 7 October 2023, Hamas began its assault with a massive rocket barrage while armed infiltrators simultaneously breached the Gaza border fence.[11] An IDF investigation reconstruction states that approximately 1,175 Hamas infiltrators entered Israel during the first wave while 1,406 rockets were fired in parallel.[11] The attackers used vehicles, motorcycles, foot routes, and motorized hang gliders; an attempted sea infiltration near Zikim was reportedly foiled by Israeli naval forces.[12] The IDF Gaza Division commander announced a major breach at 6:37 a.m., the IDF announced that Israel was at war at 6:45 a.m., and by 7:30 a.m. Hamas had seized control of the IDF Gaza Division forward headquarters at Re'im.[11]

Approximately 3,000 armed Hamas and PIJ fighters crossed the border in total, according to Israeli reporting, though other estimates put the overall number of attackers involved in the broader assault at approximately 6,000.[13][1] They fanned out across a zone extending roughly thirty miles around Gaza, striking at least 22 civilian communities, the Nova music festival near Re'im, and approximately a dozen IDF bases and posts, including a Unit 8200 base and the Sderot police station.[1][11] Fighters entered at least 31 southern communities as well as the Nova festival site and nearby military bases.[13]

The massacre at the Nova music festival alone killed at least 270 people.[13] In Kibbutz Nir Oz, more than 100 residents were killed or abducted — roughly one quarter of the entire kibbutz population.[13] Hamas forces entered Sderot, Ofakim, Israeli villages, and IDF posts, and fighting continued for hours in some locations before Israeli forces restored control.[12] It took three days for Israeli security forces to recapture all the seized communities and eliminate remaining attackers on Israeli soil.[13]

By the end of 7 October, approximately 1,200 people had been killed, the overwhelming majority of them civilians.[2][10] The dead included Jews, Muslims, Arabs, Bedouin, Druze, and nationals of at least 33 countries.[2] The attackers abducted 251 people — including babies, children, and the elderly — and transported them into Gaza as hostages.[2] Among the hostages were citizens of Argentina, China, France, Germany, the Philippines, Russia, South Africa, Sri Lanka, Tanzania, Thailand, and the United States.[2] At least 32 American civilians were killed.[2] The IDF announced a state of alert for war at 8:23 a.m., and 4,299 air-raid sirens sounded across Israel that day.[10][13] Israel began its military response under the name Operation Swords of Iron.[3]

On 8 October, Israel formally declared itself in a state of war — the first such declaration since the 1973 Yom Kippur War.[10] Prime Minister Benjamin Netanyahu warned Gaza residents: "Get out now. We will be everywhere and with all our might."[10] By that day, approximately 700 Israelis had been killed and more than 2,000 wounded; the IDF had already conducted more than 800 airstrikes in Gaza, including more than 120 strikes on Beit Hanoun during a brief period on the previous afternoon.[14]

Also on 8 October, Israel formed an emergency national unity government and a "war management cabinet" that included opposition figure Benny Gantz.[3] The Biden administration announced that it was expediting munitions already purchased by Israel and that U.S. personnel would work with Israel on intelligence sharing and hostage-recovery expertise.[2]

Hezbollah opened a northern front on 8 October, launching artillery and rocket attacks against Israeli targets and describing the strikes as acts of solidarity with Hamas.[2] The IDF responded with artillery fire and airstrikes against Hezbollah positions.[12] That same day, the IDF reported that more than 3,200 rockets had been fired at Israel since the start of the attack and that it had already struck more than 500 targets in Gaza.[12] Israel also halted its supply of electricity to Gaza; Gaza's electricity company attributed an approximately 80% electricity shortage to a fault in Israeli lines.[12]

On 9 October, Defense Minister Yoav Gallant announced a "complete siege" of the Gaza Strip, suspending the supply of electricity, food, and fuel.[15] Energy Minister Israel Katz separately announced that water supply to Gaza would also be cut off.[15] The mobilization of 300,000 reservists was announced and described as the swiftest and largest call-up in Israeli history.[2] The Qassam Brigades issued a chilling threat the same day: "We will respond by executing one of the civilian hostages. We will video the execution and broadcast it" — a threat made in response to Israeli strikes on civilian homes without prior warning.[2] The source records the statement as a threat and does not report that the threatened execution was carried out.

UN Secretary-General António Guterres warned on 9 October that Gaza's already dire humanitarian situation would deteriorate rapidly and called for humanitarian supplies and access to be permitted.[15] By 9 October, 126,000 Israelis had been evacuated from their homes, and estimates suggested that as many as 250,000 people had left homes in the south and north in total, including those not formally ordered to evacuate.[13]

By 10 October, Israel had mobilized approximately 360,000 reservists, while thousands of Israeli air and artillery strikes had struck Gaza and ground forces massed near the territory.[2] The first aircraft carrying advanced United States ammunition arrived at an Israeli air base on that day.[16] Egypt directed international aid shipments to arrive by air at Al-Arish in northern Sinai, approximately thirty miles from Gaza, as pressure mounted to establish a relief pipeline.[2]

On 11 October, Israeli operations against the attackers still inside Israel were reportedly concluded, while strikes in Gaza continued and preparations for a potential ground assault intensified.[2] Secretary of State Antony Blinken launched a regional diplomatic mission whose stated aims were to support Israel, prevent regional escalation, secure hostage releases, and address the emerging humanitarian crisis in Gaza.[2] The IDF also widened its air campaign; the Times of Israel reported that the Rafah crossing — Gaza's only land exit to Egypt — was bombed, temporarily blocking it.[17] After the southern communities had been cleared of infiltrators, the scale of the destruction became clearer: burned homes, destroyed kibbutzim, and surviving residents evacuated to hotels across Israel.[13]

On 12 October, the United Nations reported that more than 423,000 people had been forced to flee their homes in Gaza following Israeli bombardment.[18] Simultaneously, Israeli civilians organized large-scale assistance for evacuees and soldiers, preparing, collecting, and transporting equipment and meals throughout the country. The Brothers in Arms organization, which had been conducting protests against the government's judicial policies, suspended that activity and established a large civilian aid center.[13]

On 13 October, the IDF called for all civilians in northern Gaza and Gaza City to move south of Wadi Gaza "for their own safety and protection."[2] Leaflets were dropped over Gaza City, and an IDF Arabic-language spokesperson later set an 8 p.m. deadline for movement south.[19] The evacuation zone north of Wadi Gaza was estimated to contain approximately 1.1 million people, nearly half of Gaza's total population.[2] Hamas and Gaza mosques responded by urging residents to remain in place.[20]

Israel's stated purpose was to minimize civilian casualties ahead of an anticipated military escalation.[20] UN Secretary-General Guterres appealed to Israel to avert a humanitarian catastrophe, and UN officials warned that the proposed movement of 1.1 million people could have "devastating humanitarian consequences."[2] Israeli troops began localized raids into Gaza later that same day.[20]

On 14 October, the United States was working with Qatar to persuade Egypt to open the Rafah crossing to civilians and aid, while approximately 500–600 American passport holders had been advised to move toward Rafah.[21] Egyptian sources rejected opening the crossing for foreign nationals alone and insisted that aid entry and passage into Gaza had to be facilitated.[21] Egypt, however, kept the crossing closed and blocked it with concrete slabs during this period.[21]

On 15 October, Israel announced the resumption of water supply to southern Gaza, reportedly under U.S. pressure, though other supplies did not resume at that time.[2] President Biden stated that an Israeli occupation of Gaza would be "a big mistake" while reaffirming U.S. support for Israel's right to eliminate Hamas and arguing that a Palestinian authority and a path to Palestinian statehood were necessary.[2]

By 16 October, the IDF reported that 6,930 rockets had been fired at Israel since the war's beginning, more than 1,400 Israeli civilian and soldier deaths had been recorded, and 4,229 wounded people had been evacuated to hospitals.[22] Israel ordered residents of 28 communities near the Lebanese border to evacuate to state-funded guesthouses as exchanges with Hezbollah intensified.[23]

On the Hezbollah front on 16–17 October, Hezbollah claimed attacks on Israeli border posts and an Israeli tank.[22] An anti-tank missile fired at Metulla wounded three people, and another was fired at an IDF post near Margaliot.[22] The IDF reported killing a four-person terrorist squad attempting to infiltrate Israel from Lebanon on 17 October.[22] Lebanese officials indicated publicly that Lebanon wanted to avoid being drawn into a wider war.[22]

Under U.S. pressure, Israel on 16 October agreed to allow trucks carrying water and medicine to enter Gaza through Egypt, while fuel remained prohibited; Israel's stated rationale for the fuel restriction was preventing Hamas from diverting fuel to generators serving its tunnel network.[21][24] The United States and Israel announced they were developing a plan for international humanitarian aid to reach Gaza civilians, and more than 100 aid trucks were reported waiting on the Egyptian side of the Rafah crossing.[24] The European Union also announced plans for a humanitarian air corridor to Gaza through Egypt.[24]

On 17 October, an explosion occurred at or near the al-Ahli Baptist Hospital in Gaza City.[2] Hamas and PIJ blamed an Israeli airstrike and alleged that hundreds of people were killed; initial Hamas-run figures stated at least 500 deaths.[2] Israel presented evidence that the explosion resulted from an errant PIJ rocket and released video and an intercepted audio recording in support of that account.[21] U.S., Canadian, and French assessments attributed the explosion to an errant Palestinian rocket rather than an Israeli strike.[5][21] Human Rights Watch assessed that an apparent rocket-propelled munition used by a Palestinian armed group struck a paved area inside the hospital compound rather than the hospital building; later estimates placed casualties between 100 and 300 rather than the initial figure of 500.[21] President Biden stated that available evidence pointed to a Palestinian source while acknowledging continuing uncertainty.[2] The explosion and its disputed attribution dominated international coverage for days and inflamed regional tensions.

Also on 17 October, the Hamas-controlled Gaza Ministry of Health reported 2,778 Palestinians killed and 9,938 wounded since the start of the war; more than 300 tons of humanitarian aid were reportedly waiting in Egypt, and aid trucks were moving toward the Rafah crossing, which remained closed as the convoy waited on the Egyptian side.[22] The UN deputy secretary-general for emergency relief reported that approximately one million Gazans had been displaced.[22] The IDF separately estimated that Hamas, other Gaza-based terrorists, and Hezbollah had fired approximately 6,000 rockets at Israel between 7 and 16 October, including approximately 2,000–3,000 during the initial hours of 7 October alone.[2]

On 18 October, President Joe Biden became the first sitting U.S. president to visit Israel during wartime.[2] He attended a cabinet meeting, pledged continued U.S. support, and told Israeli leaders: "You are not alone."[1] Biden urged Israeli leaders not to be consumed by rage and confirmed an arrangement for humanitarian aid to enter Gaza through Egypt, subject to inspections and intended for civilians rather than Hamas.[2] He announced $100 million in humanitarian assistance for Palestinians in Gaza and the West Bank — intended to support more than one million displaced people with water, food, hygiene supplies, medical care, and other essential needs.[2]

During the visit, Biden met Rachel Edri of Ofakim, who had been held hostage with her husband in their home for 15 hours during the 7 October attack; she said she had distracted the attackers with cookies, coffee, and songs by Israeli singer Lior Narkis until Israeli forces arrived.[13]

On 19 October, the USS Carney, operating in the Red Sea, reportedly intercepted and shot down three land-attack cruise missiles and several drones launched by Houthi forces from Yemen and traveling north — potentially toward targets in Israel.[2] That same day, a trilateral committee involving Israel, the United States, and Egypt was formed to facilitate and monitor humanitarian aid entering Gaza through the Rafah crossing.[25] The IDF reported that more than 1,400 Israelis had been killed — including at least 32 American civilians — and that approximately 3,785 Palestinians had been killed and more than 12,500 injured in Gaza by that date.[2] More than one million people had been displaced, with approximately 527,500 sheltering in UNRWA schools.[2] Germany announced €50 million in aid for Gaza civilians, and Israel announced NIS 1 billion for an agency charged with rehabilitating communities along the southern Gaza border.[25]

On 19 October, the Houthis in Yemen began targeting Israel directly with drones and missiles in solidarity with Hamas, expanding the conflict's regional footprint.[1] Houthi attacks later expanded to commercial and naval shipping in the Red Sea, triggering a broader international crisis.[1]

On 20 October, Hamas released American citizens Judith Raanan, 59, and her daughter Natalie Raanan, 17 — the first two hostages released during the war — through Qatari mediation.[2] Hamas acknowledged Qatar's role in negotiating the release.[26] At the time of their release, the IDF stated that 203 people were known to have been taken hostage, with the number subject to revision as identification continued.[27]

On 21 October, the Rafah crossing opened and the first convoy of 20 humanitarian aid trucks entered Gaza from Egypt, carrying medical equipment and food transferred to the Palestinian Red Crescent under UN supervision.[4] UN aid agencies welcomed the convoy but described it as only a small beginning and far from sufficient for a population of more than two million.[4] The IDF said it had notified the families of 210 hostages being held in Gaza.[4] An international summit opened in Cairo on 21 October, attended by Jordan's King Abdullah, Egyptian President Abdel Fattah el-Sisi, Palestinian President Mahmoud Abbas, British Foreign Minister James Cleverly, and UN Secretary-General Guterres. It addressed humanitarian conditions, hostage release, regional stability, and international law but ended without a joint statement.[21]

On 22 October, a second convoy of 14 trucks reportedly entered Gaza through Rafah, and on 23 October a third convoy was reported to be waiting for security inspection.[28] By 27 October, approximately 84 aid trucks had entered Gaza through Rafah since the beginning of the war — a figure UNRWA described as covering only 3% of the medical sector's needs.[29]

On 23 October, Hamas released two additional hostages: elderly Israeli women Yocheved Lifshitz, 85, and Nurit Cooper, also identified in sources as Nurit Yitzhak, 79, both from Kibbutz Nir Oz, after mediation involving Qatar and Egypt.[30][26] Hamas stated the releases were for "compelling humanitarian and health reasons"; the husbands of both women remained in captivity.[26] Lifshitz told reporters she had been "through hell" and described being held in a "spider's web" of underground tunnels.[26] The IDF estimated that approximately 700,000 of the roughly 1.1 million residents of northern Gaza had by this point moved south.[30] The number of confirmed hostages was reported as 222, not including the four people already released.[30]

On 24 October, Hamas politburo member Ghazi Hamad told the Lebanese Broadcast Corporation: "We must teach Israel a lesson, and we will do this again and again. The Al-Aqsa Flood is just the first time, and there will be a second, a third, a fourth. Because we have the determination."[3] Additional aid trucks entered Gaza through Rafah that day, though the IDF rejected the entry of fuel.[31] The IDF confirmed that 222 hostages had been identified in Gaza.[31]

On 25 October, UNRWA warned that it would have to stop all operations in Gaza unless it received fuel.[32] Six Gaza hospitals had already shut down because of fuel shortages, and only a small number of aid trucks had entered since the prior weekend.[32] President Biden said he had suggested to Israeli leaders that delaying the ground operation could help secure the release of more hostages, while emphasizing that the ultimate decision belonged to Israel.[32]

On 26 October, the IDF acknowledged a targeted overnight raid into northern Gaza by infantry forces and tanks.[33] IDF spokesman Daniel Hagari said that limited ground raids would continue and would become more forceful in the following days.[33] The IDF reported that it had notified the families of 224 hostages, excluding the four already released.[33] Airstrikes that night destroyed underground targets, combat tunnels, combat areas, and terrorist facilities.[29]

On the night of 26–27 October, Israeli forces expanded their ground activity inside Gaza while the air force conducted an intense wave of strikes, including attacks on underground targets and terror infrastructure.[34] Hagari stated that ground forces were broadening their activity, while U.S. and Israeli officials described the operation at that moment as not yet a full-scale offensive.[34] One IDF spokesman said it was not the major operation that had been expected.[34]

On 27 October, three weeks after the war began, the IDF entered a new operational phase with a ground offensive moving into northern Gaza.[13] Armored, infantry, and engineering forces entered after heavy aerial bombardment, engaged in intense fighting, and received support from unmanned aircraft and combat helicopters.[13][29] Palestinian armed organizations continued firing rockets toward central Israel and the Beersheba area throughout the operation.[29]

Also on 27 October, the Palestinian Communications Company reported that Israeli attacks had cut international communications and internet service in Gaza.[29] UNRWA Commissioner-General Philippe Lazzarini stated that Gaza's public-health system had collapsed, UNRWA had only one day of fuel remaining, and one million people had left their homes.[29]

Hamas leader Yahya Sinwar said Hamas was prepared for an immediate exchange of all captives held by Hamas for all prisoners held in Israeli jails; Hamas military spokesman Abu Obeida said Hamas was prepared for either a single-stage or staged exchange.[29] The source presents these as Hamas statements and does not indicate that Israel accepted the proposed terms.[29]

The same day, the UN General Assembly adopted an Arab-drafted resolution calling for an "immediate, durable, and sustained humanitarian truce leading to a cessation of hostilities."[35][6] The vote was 120 in favor, 14 opposed, and 45 abstentions; Israel and the United States voted against the resolution.[35] Israel's ambassador to the UN, Gilad Erdan, stated that Israel would not stop fighting until Hamas's infrastructure was destroyed and all hostages were returned.[7] The resolution was nonbinding but politically significant, and controversy surrounded its failure to explicitly condemn Hamas for the 7 October attack.[7] Hamas welcomed the resolution and called for immediate implementation.[7]

The expansion on 27 October marked the transition from preparatory raids and an air campaign to a sustained Israeli ground offensive. During the following week, Israeli forces laid siege to Gaza City, which the Center for Israel Education described as Hamas's operational command center.[3] Israel stated that the ground campaign was intended to dismantle Hamas's military capabilities and secure the return of the hostages.[1]

From the first days of the war, the humanitarian situation in Gaza deteriorated with extraordinary speed. Israel's 9 October announcement of a complete siege — suspending electricity, food, fuel, and water — sharply restricted supplies and became one of the most internationally contested decisions of the opening phase.[15][10] Israel's stated rationale for the fuel restriction was preventing Hamas from diverting fuel to generators powering its tunnel network.[21]

Within the first few days of the war, nearly 200,000 Gazans had fled, with many seeking shelter in UNRWA schools.[21] By 12 October, the UN reported more than 423,000 displaced, and by 17 October the figure had reached approximately one million, according to the UN deputy secretary-general for emergency relief.[18][22] More than 300 tons of humanitarian aid were reportedly waiting in Egypt before any crossing was permitted.[22]

The Rafah crossing remained closed throughout most of the period before 21 October, despite intensive diplomacy. Egypt initially blocked access with concrete slabs.[21] On 19 October, Egypt announced that aid would be allowed through, but the crossing did not immediately open; more than 100 trucks were waiting at the border.[21] The first 20 trucks entered on 21 October, and a second convoy of 14 trucks followed on 22 October.[4][28] By 27 October, approximately 84 trucks in total had entered — covering, by UNRWA's account, only 3% of the medical sector's needs.[29]

Six Gaza hospitals shut down during the period due to fuel shortages, and UNRWA warned on 25 October that it would have to cease all operations in Gaza without immediate fuel deliveries.[32] By 27 October, the Palestinian Communications Company reported that internet and telephone communications had been severed by Israeli attacks.[29] The hostage situation added a specific constraint on Israeli military decision-making: Israel feared that airstrikes or special-forces operations could inadvertently kill hostages, and Hamas had threatened to execute hostages if Israeli strikes hit civilian homes without warning.[26]

The three weeks from 7 to 27 October saw intensive diplomatic activity alongside the military campaign. Secretary of State Blinken's regional tour beginning 11 October set early objectives: support for Israel, prevention of regional escalation, hostage recovery, and humanitarian access.[2] The United States expedited military aid to Israel and confirmed on 10 October that advanced U.S. ammunition was already arriving.[16]

President Biden's 18 October wartime visit to Israel — the first by a sitting U.S. president — was the most visible diplomatic event of the period.[2] The $100 million humanitarian aid announcement and confirmation of an aid-inspection arrangement through Egypt were major outcomes of the visit.[2]

Qatar served as the principal intermediary in the early hostage negotiations.[10] Its mediation produced the first two releases — American mother and daughter Judith and Natalie Raanan on 20 October — and the two elderly Israeli women released on 23 October.[2][26] Egypt participated in mediation for the 23 October releases and hosted the Cairo summit on 21 October, which brought together senior regional leaders and UN officials but concluded without a joint communiqué.[21]

On 19 October, a trilateral committee of Israel, the United States, and Egypt was established to oversee aid delivery through Rafah.[25] On 26 October, a U.S.-backed Security Council resolution calling for "humanitarian pauses" was vetoed by China and Russia.[35] On 27 October, the General Assembly passed the broader humanitarian-truce resolution by 120 votes, which Israel and the United States opposed, with Israel's representative stating that the IDF would continue fighting until Hamas's military capabilities were destroyed.[35][7]

The Houthi movement in Yemen began launching drone and missile attacks toward Israel on 19 October, claiming solidarity with Hamas; the USS Carney intercepted multiple projectiles that day.[1][2] Hezbollah continued cross-border attacks throughout the period, creating a persistent northern front and prompting Israel to order residents of 28 border communities to evacuate on 16 October.[22][23] Lebanese officials simultaneously signaled that Lebanon sought to avoid a wider war.[22]

On 24 October, UN Secretary-General Guterres addressed the Security Council, stating that the Hamas attacks did not happen in a vacuum and referring to the Palestinian experience of occupation, settlement expansion, displacement, and the absence of a political solution. The remarks drew sharp condemnation from Israel, which argued that this contextualization minimized Hamas's responsibility.[9]

Casualty and hostage figures changed repeatedly as bodies were identified and missing people were accounted for. Contemporary Israeli death totals ranged from approximately 1,200 to more than 1,400, depending on the date of the report and subsequent revisions.[2][2] Hostage counts included 203 on 20 October and 239 in a later N12 retrospective.[27][13] Other accounts used more than 240 or 253, while the later-established total was 251.[10][9]

The al-Ahli Hospital explosion on 17 October was the most contested event of the period. Hamas initially attributed it to an Israeli airstrike and claimed at least 500 deaths.[2] Israel and several subsequent U.S., Canadian, French, and Human Rights Watch assessments attributed the explosion to a misfired Palestinian rocket.[5][21] Later casualty estimates ranged from 100 to 300, but attribution and casualty counts remained politically disputed.[21]

The humanitarian consequences of Israel's 9 October siege, its evacuation orders for northern Gaza, and its restrictions on fuel and aid were fiercely contested. Israel presented the evacuation warnings as efforts to minimize civilian casualties and the fuel restrictions as measures intended to prevent diversion to Hamas's tunnel network.[20][21] UN officials and humanitarian organizations warned that moving approximately 1.1 million people could have devastating consequences.[2] Claims that Hamas obstructed civilian evacuation, fired on people attempting to leave, or diverted humanitarian resources rested largely on attributed Israeli accounts rather than independent verification.[21]

The 27 October UN General Assembly resolution was itself contested. Israel and the United States objected to its failure to explicitly condemn the 7 October terrorist attack, while the resolution's supporters emphasized the need for an immediate humanitarian truce and aid access.[35][7]

Descriptions of the 27 October Israeli operation also varied significantly. Some later accounts characterize it as the formal beginning of the ground offensive, while contemporaneous Israeli and U.S. statements described it as an expansion of ground activity or a limited incursion rather than a declared full-scale invasion.[34][13]
