Thousands of people have died and thousands more were injured after the militant group Hamas launched an unprecedented surprise attack on Israel on Oct. 7 and Israel retaliated with a bombing campaign and total siege of the neighboring Gaza Strip, leaving the region on the verge of all-out war.
At least 1,400 people have died and 4,629 others have been injured in Israel, according to Israeli authorities. In Gaza, 5,087 people have died and 15,273 have been wounded, according to the Palestinian Health Authority.
Aid workers and officials fear that Israel's call for an evacuation of the northern part of Gaza is precipitating a humanitarian disaster as electricity and other supplies have been cut off in preparation for what appears to be an imminent ground offensive.
Humanitarian groups have urged Israel to call off the evacuation and agree to a cease-fire, even as the country has asserted a right to defend itself -- a right the United States endorses.
