Israel has targeted Hamas leader Mohammed Sinwar in a strike on a hospital in southern Gaza on Tuesday evening, according to a senior Israeli official and two sources familiar with the matter.

Israeli officials said the military had launched an attack targeting Mohammad Sinwar, one of Hamas’s top remaining commanders in Gaza and the brother of a leader killed last year.

Hamas says it will release an American-Israeli hostage held in Gaza later in the day. The Palestinian militant group said Edan Alexander would be freed on Monday as a goodwill gesture to the Trump administration.
