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.

Israel carried out massive strikes on a hospital complex in southern Gaza on Tuesday, causing chaos at the facility, overturning concrete on roads and in the courtyard, and leaving gaping craters from a raid the military said targeted an underground bunker used by Hamas.

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.
