Israel’s prime target: the hunt for Hamas leader Yahya Sinwar

Motivated pursuers using advanced technology and brute force have yet to pin down their cautious quarry. Would his death or capture stop the war?

A group of Israeli hostages were huddled in a tunnel in Gaza a few days after they had been dragged from their homes on 7 October, when the man who had plotted their abduction appeared out of the subterranean gloom.

His hair and beard were grey and his dark-ringed eyes stared out from under thick black brows. It was a face familiar to them from a thousand broadcasts and newspaper stories: Yahya Sinwar. The Hamas leader in Gaza was the most feared man in Israel, even before he ordered the October raid in which 1,200 people - two-thirds of them civilians - were killed and 250 taken hostage.
