Kathmandu. Hamas confirmed Friday that its leader, Yahya Sinwar, was killed by Israeli forces in Gaza and reiterated its stance that hostages the militant group took from Israel a year ago will not be released until there is a cease-fire in Gaza and a withdrawal of Israeli troops.

The group’s staunch position pushed back against a statement by Israeli Prime Minister Benjamin a day earlier that his country’s military will keep fighting until the hostages are released and will remain in Gaza to prevent a severely weakened Hamas from rearming.

Sinwar was the chief architect of the Hamas raid on Israel last year that killed some 1,200 people, mostly civilians, and kidnapped another 250. Israel’s retaliatory offensive in Gaza has killed over 42,000 Palestinians, according to local health authorities, who do not distinguish combatants from civilians but say more than half the dead are women and children.

The war has destroyed vast swaths of Gaza, displaced about 90% of its population of 2.3 million people and has left them struggling to find food, water, medicine and fuel.
