The Iranian-backed group Hamas, long designated a terrorist organization by the U.S. and Israel, launched an unprecedented attack on Israel on Oct. 7, 2023. The massacre of some 1,200 people ignited a devastating war in the Gaza Strip, a densely-packed Palestinian territory that had been ruled by Hamas for almost two decades. The Hamas-run Ministry of Health says Israeli military operations in Gaza since Oct. 7 have killed almost 42,000 people. 

Below is a timeline showing some of the key events in the year that has passed since many Israelis’ sense of security was shattered on that Saturday morning.

October 7, 2023 

• The ruling Hamas militant group in the Gaza Strip carries out an unprecedented, multi-front attack on Israel at daybreak, infiltrating the heavily fortified border in several locations by air, land and sea, catching the country off-guard on the Jewish holiday of Rosh Hashanah. The stunning attack sees Hamas terrorists and other militants kill more than 1,200 people, including 43 U.S. nationals. Israel says 251 others were taken hostage during the attack, with many of the abductions captured on cameras worn by the terrorists themselves and then circulated on social media. “We are at war,” Israeli Prime Minister Benjamin Netanyahu announces in a televised address later that morning, declaring a mass mobilization of the country’s army reserves. Israel launches retaliatory airstrikes in Gaza, saying it is targeting Hamas fighters and weapons, almost immediately.

• The first of what would become many disturbing hostage videos over the course of the war is shared by Hamas on its Telegram messaging app channel. The video shows 21-year-old French-Israeli national Mia Shem lying on a bed with her injured right arm appearing to be treated by somebody out of the camera’s view. Shem appears distressed as she speaks directly to the camera, saying she’s been taken to the Hamas-controlled Gaza Strip and pleading to be returned to her family. Shem’s mother tells CBS News she can see her daughter’s pain, and hopes the video is an indication of Hamas’ willingness to negotiate a hostage release deal.

• Health officials in Gaza say hundreds of people are killed in a huge blast at the Al-Ahli Baptist Hospital in Gaza City, and Israeli and Palestinian officials trade accusations over who is responsible for the devastating explosion. U.S. intelligence officials say between 100 and 300 people were likely killed in the blast, which Palestinian officials blame on an Israeli airstrike. Israeli officials say they did not target a hospital and that an intelligence review indicates the explosion was caused by a rocket launched by the Hamas-allied militant group Islamic Jihad that fell short. President Biden says soon after the explosion that, from what he’s seen, it appears as though it was not caused by an Israeli strike.

The allegations against UNRWA staffers prompted the U.S. and some other Western countries to freeze funds vital to the work of the agency, which is a lifeline for desperate Palestinians in war-torn Gaza. The U.N. later fires nine of the 12 accused workers and condemns “the abhorrent alleged acts” of some of its staff.
