WASHINGTON: A top US military commander responsible for the Middle East and the Gulf region said the United States has developed contingency plans to deal with Iran's nuclear facilities, insisting that they "can be bombed." "Well, they certainly can be bombed," General David Petraeus, head of US Central Command, told CNN as he commented on suggestions that Iranian nuclear facilities were heavily fortified. "The level of effect would vary with who it is that carries it out, what ordnance they have, and what capability they can bring to bear," he said.
