“The U.S. didn’t assign responsibility for the shelling,” which the U.N. said was carried out by Israeli forces, when it condemned this morning’s attack on a school housing 3,300 displaced Palestinians in Gaza, the AP reports. But the White House is “extremely concerned” that the shelters aren’t safe. “All of these actions, and similar ones earlier in the conflict, are inconsistent with the U.N.’s neutrality,” said a spokesperson. “This violence underscores the need to achieve a cease-fire as soon as possible.” Meanwhile, the U.S. is also sending more ammunition to the IDF.
