Secretary of State Antony Blinken’s comments were the strongest yet from a U.S. official after the Israeli military said it was “highly likely” it “unintentionally” killed Aysenur Eygi.

Israel launched its largest airstrike targeting the West Bank since the start of the war, killing 18 Palestinians, including a local Hamas leader. While the Israel Defense Forces have been locked in conflict in Gaza and Lebanon,

Hamas confirmed that commander Zahi Yaser Abd al-Razeq Oufi was killed by the strike, who the IDF say attempted a car bombing last month and supplied weapons. The Israeli military said the air strike was a joint operation with its Shin Bet security service, aimed at killing Oufi and "other significant terrorists".
