CNN's John Roberts talked with John Ging who is the director of UNRWA in Gaza. Ging believes that Israeli shells that recently struck the U.N. complex contained white phosphorus. "It looks and smells like phophorus and it's burning like phophorus. That's all i can say. That's why i'm calling it phophorus," said Ging.

The complex under fire is the U.N. central distribution facility in Gaza. "We're trying to deal with our whole transport compound. It's on fire and now have some danger spreading into the warehouse, where all of the food and thousands of tons of food and medicine. This is a hub of the whole operation, the whole United Nations operation in Gaza, this is the hub, where it all comes to, gets distributed from," he said.

Three people have been reported as injured in the attack.
