U.N. Chief: Attack At School In Gaza 'Criminal Act'

U.N. Secretary-General Ban Ki-moon says an attack that killed 10 people at a U.N. school in the Gaza Strip is a "moral outrage and a criminal act."

Ban says the attack Sunday "is yet another gross violation of international humanitarian law, which clearly requires protection by both parties of Palestinian civilians, U.N. staff and U.N. premises, among other civilian facilities."

In a statement, the U.N. chief said the attack "must be swiftly investigated and those responsible held accountable. It is a moral outrage and a criminal act."
