Hamas has announced it will release the man believed to be the last living U.S. citizen held hostage in Gaza, the group announced Sunday.

Edan Alexander was snatched from his military base in southern Israel during Hamas’ cross-border attack on Oct. 7, 2023, which set off the war in Gaza. His expected release would be the first since Israel shattered an eight-week ceasefire with Hamas in March, when it unleashed fierce strikes on Gaza that have killed hundreds.

Hamas will release Israeli-American hostage Edan Alexander from Gaza on Monday, the Palestinian militant group said, although Israel's prime minister said there would be no ceasefire and plans for an intensified military campaign would continue.
