US warns of 'specific, credible threat' near Kabul airport

The United States warned Saturday of a "specific, credible threat" near Kabul airport and urged its citizens to leave the area, days after a deadly attack on crowds fleeing Taliban rule in Afghanistan. A series of urgent terror warnings have rattled evacuation efforts overseen by US forces, who have been forced into closer security cooperation with the Taliban to prevent a repeat of Thursday's carnage at one of the facility's main access gates.
