Citing an "unimpeachable source," Osama bin Laden and his al-Qaida deputy Ayman al-Zawahiri are in Iran, according to a Fox News analyst.

Al-Zawahiri was seen within the last two weeks, and bin Laden was spotted in October, says the network's foreign affairs analyst.

Bin Laden is wearing a shorter beard that is dyed to make him look more like an Iranian cleric. He also has put on a considerable amount of weight.
