U.S. President Barack Obama and Turkish Prime Minister Recep Tayyip Erdogan discussed the rocket attacks in a Friday telephone call.  White House officials say both men share concerns about the dangers to civilians and agreed that the violence jeopardizes prospects for a durable, lasting peace in the region.

Secretary of State Hillary Clinton spoke with Jordan's King Abdullah and the Egyptian and Israeli foreign ministers. State Department spokeswoman Victoria Nuland addressed the seriousness of the conflict.

"We have an extremely dangerous and volatile situation. We have a dangerous situation inside Gaza. We have a dangerous situation inside Israel," said Nuland.
