Hamas's October 7 massacre: Reliving the day, hour by hour

One year ago today, Hamas terrorists invaded southern Israel, massacring thousands of Israelis and foreign nationals and taking hundreds more hostage, launching Israel into an unprecedented year of threats, attacks, assassinations, protests, and war.

Some 1,200 people were killed in the Hamas-led October 7 massacre. Over 250 people were kidnapped into the Gaza Strip, with 101 of them still being detained in captivity.

To honor the memory of the fallen and those taken hostage, the Jerusalem Post has created a timeline of the harrowing events of October 7 in hopes of memorializing and eternalizing the sacrifice of those Israelis murdered by terrorists in their homes, as well as the bravery of hostages who remain in the Gaza Strip, 12 months on.

October 7 massacre: Waking up to nightmares

6:29-6:50 a.m.: First sirens sound in the Gaza border communities of Nahal Oz, Ofakim, Kfar Aza, Nir Oz, Kissufim, and Be'eri, as well as the city of Sderot.

Only a few moments later, sirens sound across southern Israel and the Shfela region, as well as in Tel Aviv and nearby cities in central Israel. At this point, most of the nation was hiding in shelters.

Amid the heavy rocket fire, IDF field observers at the Nahal Oz outpost identify two gunmen running towards the fence. They also see terrorists detonating parts of the border fence. At 6:45 a.m., system disruptions at the outposts lead to some 70 terrorists raiding the base, with more joining the murderous raid later in the morning.

In Kfar Aza, Ynet photographer Roi Idan takes the first footage of Hamas paragliders entering Israel. Minutes later, his wife, Smadar, is killed before he himself is murdered while holding his three-year-old daughter, Abigail.

Some 3,500 revelers attended the Nova music festival near Kibbutz Re'im the night before. When the first interceptions and blasts were heard, they were told to lie on the ground and protect their heads with their hands despite no sirens being triggered in the area. At 6:32 a.m., party organizers announced the event had ended and called on everyone to leave. Most left towards the car park.

6:50: Hundreds of terrorist invaders begin entering Israeli towns, from terrorists on jeeps seen driving through Sderot to infiltrations of Be'eri, Kissufim, Ofakim, and Nahal Oz. By 7:20 a.m., an emergency standby squad of the kibbutz near the Erez crossing identifies some 20 terrorists making their way towards the kibbutz.

A traffic jam ensues at the exit from the Re'im festival area as only one route, Route 232, leads out of the car park. Terrorists who infiltrated the Gaza Strip and saw the movements of cars in the area opened fire at the vehicles shortly before seven, barring the exit. Hostages were taken on the scene.

7:00: Party-goers escape from their cars to the nearby fields as the terrorists are pursuing them. Many hide in the fields, wounded. More hostages were taken into Gaza. Many who already left the party area did not know of the terrorist invasion. Upon hearing the sirens, they sought refuge in mobile bomb shelters along Route 232. When the terrorists saw them, they hurled grenades at them. Nahal combat soldier Aner Shapira, who hid in one of the shelters, managed to fend off seven of the grenades before he was killed. His close friend Hersh Goldberg-Polin, who was with him, was taken hostage along with Eliya Cohen and Or Levy.

7:50: Footage surfaces of armed terrorists driving white pick-up trucks in the southern city of Sderot, spreading quickly on social media and news outlets and sowing panic among Israelis.

7:53: IDF issues the first official response, stating Hamas carried out a combined operation involving rocket fire and terrorist infiltrations.
