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.

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.

The American dual national Edan Alexander has been handed over by Hamas more than 19 months after he was taken hostage.
