The Biden administration "must respond to the reported execution-style massacre of women, children, and babies," said the spokesperson of a U.S. Muslim advocacy group.

Eyewitness testimony reported Wednesday by Al Jazeera accused Israeli troops of massacring forcibly displaced women and children sheltering at a school in northern Gaza,

The Israeli soldiers came in and opened fire on them," one unidentified witness said. “They took all men, then entered classrooms and opened fire on a woman and all the children with her,” including “newborn children.”

“The Israeli soldiers executed those innocent families point-blank,” she added.

A man who arrived at the scene after the alleged mass murder told Al Jazeera that “we found dozens of dead bodies in the classrooms.”

“There is no sign of any missiles or shells,” he added. “All those who were in the buildings were executed from point-blank. The Israeli soldiers opened fire on them. Many families came searching for their children. They found them all killed. They were all killed, executed at gunpoint.”
