Four foreign security guards were killed and six others injured when a suicide bomber on a motorcycle targeted a police compound in Kabul, Afghan officials said.
Deputy interior minister General Mohammad Ayoub Salangi said the attacker targeted the compound in the capital which houses foreign advisers to the Afghan government as well as the office of the deputy minister for counter-narcotics.
A police spokesman, Sayed Mahdi Kazimi, said the bomber managed to reach the entrance gate of the compound and detonated his motorbike packed with explosives.
The nationality of the dead guards was not immediately disclosed.
Taliban spokesman Zabihullah Mujahid claimed responsibility for the attack in a statement sent to media.
The Taliban frequently use roadside bombs and suicide attacks against Afghan and Nato forces and government offices in the country.
