Israel says it's "checking the possibility" that it killed Hamas leader Yahya Sinwar during a military operation in Gaza - but adds it is not confirmed. Sinwar is believed to be a key figure in the planning and execution of the 7 October attacks on Israel last year. In a statement, the Israel Defense Forces says the identity of "three dead terrorists" had yet to be confirmed. "In the building where the terrorists were eliminated, there were no signs of the presence of hostages in the area," the IDF said.
