Three men including the last living American-Israeli civilian held in Gaza were freed in a propaganda-tinged event that was calmer than many previous releases.

Mr. Trump made the comments about the hostages while signing executive orders on Monday at the White House. He spoke hours after Hamas said it was delaying the next release of hostages, which was scheduled for Saturday, as a spokesman accused Israel of violating the ceasefire agreement, including by targeting Palestinians in Gaza with airstrikes.
