Israel and Hamas agreed to a deal to halt fighting in Gaza and exchange Israeli hostages for Palestinian prisoners, an official briefed on the deal told Reuters on Wednesday, opening the way to a possible end to a devastating 15-month conflict.
Israel and Hamas have been at war in Gaza since gunmen from the Palestinian militant group attacked southern Israel on Oct. 7, 2023, killing 1,200 people and capturing over 250 hostages, according to Israeli tallies.
Israel responded with a military campaign in which more than 46,000 Palestinians have been killed, according to medical officials in the enclave, with thousands more feared buried under the rubble.
Here is a timeline of the war:
