More than a year after Hamas’ devastating October 7 attacks on Israel, the country’s military said Thursday it had killed the man it considers to have been the chief architect of that cross-border incursion – raising questions about the future of the war and of the militant group itself,

The US said it would push toward a cease-fire in Gaza after Israel killed Yahya Sinwar, the leader of Hamas and the mastermind of the Oct. 7 attacks that ignited a yearlong war in the Palestinian enclave.

Israeli Prime Minister Benjamin Netanyahu said Thursday that the killing of Hamas chief Yahya Sinwar in the Gaza Strip was the "beginning of the end" of the year-long war in the Palestinian territory.
