**A suicide car bomber has targeted the military airport in the Afghan capital, Kabul, reports say.**The explosion occurred outside the main gate of the airport’s military base, causing a large plume of smoke, reports and police officials say.
There are some reports of casualties, but details are still sketchy.
The airport is used as a base by the Nato-led forces fighting the Taliban. A US military spokesman confirmed the blast, but gave no details.
Witnesses described flames rising from the site of the explosion, which rattled windows in the centre of the city.
The airport has been targeted in the past by suspected Taliban militants.
In 2007, at least one person was killed and four injured in a suicide bomb attack on the airport.
