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.

An Israeli airstrike on the Gaza Strip on Tuesday killed a well-known Palestinian journalist whom it accused of working with Hamas and was recovering in hospital from an earlier strike, the territory's health ministry said.

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.
