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.

The strikes hit the European Hospital complex in Gaza, with reports suggesting Israel was trying to kill a high-level Hamas target.

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.
