The threat which has prompted the U.S. to shutter some diplomatic posts and issue a travel alert is reportedly based on intercepted communications.

The New York Times is reporting that the communications were between senior al-Qaida operatives.

The top U.S. military commander says there is what he calls "a significant threat stream." Joint Chiefs Chairman Gen. Martin Dempsey told ABC News that the threat was "more specific" than previous ones and that potential targets are Western, not just U.S. interests."

The State Department is urging American travelers to take extra precautions overseas. Potential dangers listed include public transportation systems and other prime sites for tourists.

The threat follows this week's White House meeting between President Barack Obama and Yemen's current president, Abdo Rabby Mansour Hadi.
