A suicide bomber has targetted the main airport in the Afghan capital of Kabul killing two civilians, according to officials.
The interior ministry said six people were also wounded in the attack at 8.30am on Tuesday. Witnesses say a car bomber rammed the main gate of the airport's military base, the BBC reports.
One witness said they saw a four-wheel drive vehicle exploding near a foreign military convoy.
Nato-led forces fighting the Taliban have a base at the airport, which is used by civilian and military aircraft.
The BBC's says there are unconfirmed reports that members of Nato's International Security Assistance Force were among the casualties.
In 2007, at least one person was killed in a suspected Taiban suicide bomb attack at the airport.
