"...A spokesman for the United Nations Relief and Works Agency said two children died when the school in northern Gaza, which was being used as a shelter, was struck by an Israeli tank shell. ...“The Israeli army knew the coordinates of this installation,” UNRWA spokesman Christopher Gunness said in a telephone interview. “There has been a direct hit on a UN school sheltering hundreds of people. There has to be an investigation for possible war crimes.”

It was the first time a UN official has called for a war crimes investigation over Israeli attacks on its installations in Gaza since the military operation began.

There were no reports of Hamas fighters firing from the school, Gunness said. “Israel keeps giving that excuse. Their credibility hangs in rags,” he added.

An Israeli military spokesman said all alleged incidents of hits on such civilian installations are being investigated, and it will take time. The credibility of an investigation is more important than speed, he said."
