At least four people, including three foreign advisers, have been killed as a Taliban suicide bomber detonated himself at the Kabul International Airport.

The incident took place at about 07:00 local time in Qasaba area. The fourth victim was an Afghan interpreter.

Taliban has claimed responsibility for the bombing.

Eyewitness reports said the assailant rode his bike in front of a building before setting off explosives. Several others have been injured in the attack.

"In this successful attack up to 15 invader soldiers were killed or wounded and many vehicles were damaged," said Taliban spokesperson Zabihullah Mujahid, according to Reuters.

An eyewitness said: "It was early morning and I was asleep. Suddenly an explosion woke me up. We were told that there was a suicide attack inside a foreign base. There was human flesh (lying) outside the base. We tried to go inside the base to find out what had happened but there were Americans who didn't let us in."

A local report in Khaama Press cited an Afghan police official as saying that at least 10 people were killed in the attack.

The nationalities of the foreign victims are yet to be ascertained. The airport is a major base for Nato forces, which have been battling Taliban insurgency since 2002.

The airport had come under another intense attack recently.
