(CNN) - Using some of its strongest language since the fighting began, the Obama administration condemned the shelling of a U.N. shelter in Gaza today - though in very careful wording.
"We do condemn the shelling of an UNRWA school in Gaza, which reportedly killed and injured innocent Palestinians including children and U.N. humanitarian workers," said Deputy States Department Spokeswoman Marie Harf, adding," Of course we would also condemn those responsible for hiding weapons in United Nations facilities in Gaza as well."
The U.N. school, used as a shelter for three thousand Palestinians in Gaza, is in shambles after shelling it killed at least twenty people. Many more are wounded, according to Palestinian officials.
While the White House is not directly accusing Israel of striking U.N. shelters - or Hamas of hiding weapons in them for that matter - the U.N. is.
"All available evidence points to Israeli artillery as the cause," declared Secretary General Ban Ki-moon today.
Israel has not claimed responsibility, though its military did admit that a group of militants fired at Israeli soldiers from the area of the school, and the soldiers returned fire.
Harf suggested that is Hamas's pattern.
"Look, the reason these civilians are unsafe is because Hamas has had a pattern of hiding weapons, of hiding fighters, in these schools. So that - Hamas has put these civilians at risk."
All this comes as CNN has learned that Israel wants the US to resupply it with ammunition.
