The American CNN network revealed that "the Israeli army used American weapons in its attack on an UNRWA school housing displaced Palestinians in the Nuseirat camp" in the central Gaza Strip.

CNN's analysis of a video clip from the site of the Nuseirat massacre and a review conducted by an explosive weapons expert (which it did not name) concluded that American-made munitions were used in the attack on the UNRWA school.

CNN identified fragments of at least two American-made GBU-39 Small Diameter Bombs (SDB) in a video clip taken by a journalist working for the same network at the scene of the attack.
