On Tuesday night, Israeli fighter jets bombarded the southern Gaza city of Khan Younis in an effort to kill Muhammad Sinwar, one of the group’s top remaining military commanders. The Israeli military said it had targeted a Hamas complex underneath the European Hospital near Khan Younis.

Israel launched dozens of airstrikes across Gaza on Friday that local health officials said killed 108 people, mostly women and children, and which Israeli officials described as a prelude to a stepped-up campaign to pressure Hamas to release hostages.

At least 22 children were killed in Gaza overnight Tuesday and early Wednesday in a punishing series of Israeli airstrikes on homes in northern Gaza, according to local hospitals.
