Obama's North Africa problem, warns Americans to stay out

The U.S. is warning Americans to stay out of Benghazi, Libya  - site of the deadly attack on the U.S. mission four months ago.

That comes as the British government warns of a "specific and imminent threat to Westerners" in the city. Germany and the Netherlands also urging their citizens to leave Benghazi immediately.

The terror threat in north Africa is a growing concern for the Obama administration - one that's opening up a divisive debate about what the U.S. should do.
