One attacker in an explosives-packed vehicle blew himself up at the entrance of the base in Nangarhar province, and five other insurgents were shot as they tried to storm the facility.

Nato's International Security Assistance Force (Isaf) confirmed one fatality in a suicide attack in the east of the country, without giving further details.

Afghan and Western officials said the attack took place in Shinwar district, a volatile area on the main highway from Kabul, where many Taliban insurgents seek shelter.

"Around 8:00 am, a suicide bomber detonated himself and the other five were gunned down by Afghan security forces. Their bodies lie at the scene," Ahmad Zia Abdulzai, spokesman for the Nangarhar governor, told AFP.

In an emailed statement to the media, Taliban spokesman Zabihullah Mujahid claimed responsibility for the attack.
