Sinwar's death is serious blow to Hamas, but not the end of the war

Every leader of Hamas since the 1990s has been killed by Israel, but there's always been a successor. As Israel celebrates killing Sinwar:
1. Hamas still has its hostages
2. and is still fighting

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.

according to the BBC:
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.

In his 20s, he was convicted by Israel of killing four Palestinian informers.
During 22 years in jail he learnt Hebrew, studied his enemy and believed that he worked out how to fight them.

His time in jail also meant Israel had his dental records and a sample of his DNA, which meant that they could identify his body.
