At least 14 others were wounded in the blast, local district governor Haji Shookor told the BBC. The Taliban said one of their suicide bombers had carried out the attack, which reportedly hit a dining area. The attack is being seen as a major security breach in one of the best protected places in Afghanistan.

He said the incident was being investigated but did not disclose the nationalities of the casualties.


Taliban spokesman Zabihullah Mujahid said the blast had inflicted "heavy casualties on US invaders".


Last December, a Taliban suicide bomber riding a motorbike killed six US soldiers in a village near Bagram in one of last year's deadliest attacks on foreign troops.

The attack on Bagram comes just a day after the German consulate in the city of Mazar-e-Sharif in northern Afghanistan was hit by a Taliban suicide bomb blast that killed six civilians and wounded some 120 others.


The Taliban said on Friday the attacks were carried out in retaliation for a recent coalition airstrike in Kunduz which reportedly killed some 30 civilians.


Correspondents say the Taliban are stepping up their attacks before the onset of winter.
