This is the best summary I could come up with:

President Joe Biden addressed Jewish community leaders at a round table on Wednesday, where he referenced a gruesome claim made by the Israel Defense Forces.

Later in the evening on Wednesday, a National Security official told NPR that Biden was referring to media reports when he made that remark.

Later on Tuesday, IDF spokesman Major Nir Dinar told Insider that Israeli soldiers came across the bodies of babies, including some that had been decapitated, at the Kfar Aza kibbutz near the Israel-Gaza border.

Dinar said the IDF "can not confirm any numbers," but described the situation at the kibbutz as a "massacre" in which children were "brutally butchered in an ISIS way of action."

Dinar said the claim of decapitated babies was made based on what soldiers on the ground had relayed to him and others in the military.

As of Wednesday afternoon, Palestinian authorities said 1,100 people in Gaza have been killed, including at least 260 children.
