"Blaming Israel for an attack that killed several people at a school in Gaza, the United States said it was "appalled" by the "disgraceful shelling" -- sharp criticism from Washington rarely heard when Israel is engaged in battle.

"When you have a situation where innocent civilians are killed in Gaza, there's more that Israel can do to hold themselves to their own standards," State Department spokeswoman Jen Psaki said."
