Rick Santorum warned voters in New Hampshire that Iran may use nuclear weapons to bring about the end of the world.

He claimed that Iran President Mahmoud Ahmadinejad's mention of the the 12th Imam, Muhammad al-Mahdi, in his speeches could be a hint that he wants to use the weapons to bring this savior back.

Believers say that Muhammad al-Mahdi will return just before the end of the world as populations fall into conflict.
