Israeli hostage Edan Alexander, who had been held captive by Hamas in Gaza since Oct. 7, 2023, was released on Monday after successful negotiations between the U.S. and the terrorist organization, the Israel Defense Forces said.

Edan Alexander, the last known living American hostage in Gaza, was released by Hamas on Monday, ending an 18-month ordeal that began with the militant group’s October 7 attack.

Hamas has released an Israeli-American hostage held captive for 19 months to Israeli forces as part of efforts to reach a new ceasefire deal, the group said. Edan Alexander, 21, had been serving in the Israeli army on the border of Gaza when he was captured by Hamas militants on 7 October 2023.
