Afghan officials say a suicide bomb blast has killed at least two security guards at a foreign compound in Kabul.
An interior ministry spokesman said a small truck packed with explosives rammed the gate of a foreign base in the Pul-e-Charkhi district of the capital city early Tuesday morning.
The Taliban claimed responsibility for the attack.
The explosion rattled windows several kilometers away in Kabul's central diplomatic district and sent up a massive plume of smoke.
The area where the blast took place has a number of compounds housing foreign companies, as well as international military bases but it was not clear which was targeted. The Afghan government's intelligence agency also has a branch nearby.
According to analysts, bomb attacks targeting foreign troops and Afghan government officials and security forces have intensified as the international military coalition draws down, leaving the fight against the Taliban insurgency mostly to Afghan forces.
On Sunday Afghan lawmaker Shukria Barakzai escaped a suicide blast in Kabul as she drove in a convoy near parliament. Three civilians died in that attack.
