KABUL: A Taliban suicide attacker riding a motorbike killed at least four foreigners in a compound in Kabul on Tuesday, police said, in the latest blast to rock the capital during a prolonged impasse over presidential election results.
"Our initial reports show the explosion took place inside the foreigners' compound four foreigners were killed and six were wounded," Kabul police chief Zahir Zahir told AFP.
"The foreigners were exercising inside at the time."
"Our teams are on the ground investigating how an attacker on a motorcycle entered the compound."
The nationalities and jobs of the victims was not known, and there was no immediate comment from NATO's International Security Assistance Force (ISAF), which is winding down its mission this year after a 13-year war against the Taliban.
"The camp is used by the ministry of interior's counter-narcotics department, but we don't know whether those killed were advisors to the ministry," Najib Danish, deputy spokesman ministry of interior, told AFP.
Another government official said the victims worked for a private contractor.
The Taliban used a recognised Twitter account to claim responsiblity for the attack, saying 15 "agents" had been killed inside a foreign intelligence base.
The insurgents often exaggerate death tolls after attacks. (AFP)
