WASHINGTON (AP) — President Joe Biden says that the U.S. will begin air-dropping humanitarian assistance into Gaza, a day after more than 100 of Palestinians were killed during a chaotic encounter with Israeli troops. The president announced the long-considered move on Friday after at least 115 Palestinians were killed and more than 750 others were injured, according to Gaza’s Hamas-run health ministry, on Thursday when witnesses said nearby Israeli troops opened fire as huge crowds raced to pull goods off an aid convoy.Israel said many of the dead were trampled in a stampede linked to the chaos and that its troops fired at some in the crowd who they believed moved toward them in a threatening way. Biden made the announcement while hosting Italian Prime Minister Giorgia Meloni at the White house.
