A suicide bomber on a motorbike has killed at least four people in an attack on a police building in Kabul, Afghanistan.
The camp is used by the ministry of interior's counter-narcotics department, AFP news agency reported on Tuesday.
Deputy interior minister, General Mohammad Ayoub Salangi, said the attacker targeted a compound that housed foreign advisers to the Afghan government as well as the office of the deputy minister for counter-narcotics.
The Taliban claimed responsibility for the attack, which left at least six others wounded. The nationalities of those killed and injured in the blast have not been announced.
Taliban spokesman, Zabihulllah Mujahid, said: "In this successful attack up to 15 invader soldiers were killed or wounded and many vehicles were damaged." The death toll claimed by the Taliban has not been confirmed.
The bomber was reportedly wearing an Afghan intelligence police uniform, police sources told Al Jazeera.
There was no immediate comment from NATO's International Security Assistance Force, which is winding down its 13-year mission in Afghanistan.
