JERUSALEM 

The Israeli army said Thursday it is checking the possible killing of Hamas leader Yahya Sinwar in a military operation in the Gaza Strip.  

A military statement said three Palestinians were killed during a joint operation by the army and the Shin Bet security service. 

We are "checking the possibility that" one of them was Yahya Sinwar, it added, without providing further details.
