The United States issued an extraordinary global travel warning to Americans Friday about the threat of an al-Qaida attack and closed down 21 embassies and consulates across the Muslim world for the weekend.
The alert was the first of its kind since an announcement preceding the tenth anniversary of the 9/11 terrorist attacks. This one comes with the scars still fresh from last year's deadly Sept. 11 attack on a U.S. diplomatic post in Benghazi, Libya, and with the Obama administration and Congress determined to prevent any similar breach of an American Embassy or consulate.
"There is a significant threat stream and we're reacting to it," said Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff. He told ABC News in an interview to be aired Sunday that the threat was "more specific" than previous ones and the "intent is to attack Western, not just U.S. interests."
