US military chief in Iran warning

Iran has enough nuclear material to build a bomb, the US' most senior military commander has said.

"We think they do, quite frankly," Adm Mike Mullen, chairman of the US Joint Chiefs of Staff, told CNN.

"And Iran having a nuclear weapon, I've believed for a long time, is a very, very bad outcome for the region and for the world," he said.

Iran says its nuclear programme is entirely peaceful, but the West suspects it is seeking nuclear weapons.
