One American, Edan Alexander, had been among the 24 hostages believed to be alive, with the bodies of several other Americans also held by Hamas after its Oct. 7, 2023 assault on Israel.
The president's comments came as Israel approved plans on Monday to seize the Gaza Strip and to stay in the Palestinian territory for an unspecified amount of time, in a bid to recover the hostages and try to fulfill its war aims of destroying Hamas. If implemented, the move would vastly expand Israel's operations there and likely draw fierce international opposition.
