The Gaza ceasefire deal has come into effect. It is set to pause the fighting after 15 months of war and see the release of dozens of hostages held by the militants in the Gaza Strip and hundreds of Palestinians imprisoned by Israel. Brokered by mediators the United States, Qatar and Egypt in months of indirect talks between the warring sides, the ceasefire is the second truce achieved in the devastating conflict. The Hamas-led Oct. 7, 2023, attack on southern Israel killed some 1,200 people and left some 250 others captive. Nearly 100 hostages remain in Gaza. Israel responded with an offensive that has killed more than 46,000 Palestinians, according to local health officials, who do not distinguish between civilians and militants but say women and children make up more than half the dead.
