Every Hamas leader since the 1990s has been killed by Israel but there has always been a successor

 

Killing Yahya Sinwar is Israel's biggest victory so far in the war against Hamas in Gaza.

His death is a serious blow for Hamas, the organisation he turned into a fighting force that inflicted the biggest defeat on the state of Israel in its history.

He was not killed in a planned special forces operation, but in a chance encounter with Israeli forces in Rafah in southern Gaza.

A photo taken at the scene shows Sinwar, dressed in combat gear, lying dead in the rubble of a building that was hit by a tank shell.
