VIDEO: Anger grows over Gaza school attack

Jan 7 - Residents of Jabalya in northern Gaza have held funeral processions for the dozens of Palestinians were killed during an Israeli strike on a UN school.

Arab and widespread international anger mounted on Tuesday when Israel acknowledged hitting a U.N. school where hundreds of people were taking refuge. Medics said 42 people were killed.

Israel accused Hamas of using civilians as "human shields" and said troops had been returning mortar fire from the school.

But a spokesman for the United Nations Relief and Works Agency said he was virtually certain there were no Palestinian militants inside the school grounds.
