Israeli forces opened fire while a crowd was gathered on Thursday near a convoy of trucks carrying desperately needed aid to Gaza City. The details of what happened were unclear, with officials from both sides offering starkly different accounts. The Gazan health ministry said in a statement that more than 100 people were killed and more than 700 injured in a “massacre.” Israeli military officials said most of the casualties were from a stampede of Gazans as they crushed around the aid trucks. President Biden said he was still learning details of what happened, but believed the deaths could jeopardize diplomatic talks.
