JERUSALEM (Reuters) -Hamas leader Yahya Sinwar was tracked by an Israeli mini drone as he lay dying in the ruins of a building in southern Gaza and filmed him slumped in a chair covered in dust, according to video released by Israeli authorities on Thursday.

Intelligence services had been searching for Sinwar for months and had been gradually restricting the area where he could operate, the military said on Thursday, after dental records, fingerprints and DNA testing provided final confirmation of Sinwar's death.
