The US State Department is urging all Americans in the vicinity of the Afghanistan`s Kabul airport to leave the area immediately because of a specific, credible threat.

The warning early Sunday morning says US citizens should avoid traveling to the airport and avoid all airport gates at this time. It specifically noted the South (Airport Circle) gate, the new Ministry of the Interior, and the gate near the Panjshir Petrol station on the northwest side of the airport.
