Kabul, Jan 5 (IANS): A bomb attack took place Saturday night at a NATO military base in Wazir Akbar Khan, a diplomatic enclave in the Afghanistan's capital Kabul, police said.

"The blast took place after a military convoy entered the Camp Eggers, a NATO base near the German embassy in street 17 Wazir Akbar Khan district. Since the incident occurred inside the base the casualties remain unknown," Xinhua quoted a police source as saying.

Media reports said that the blast was caused by a sticky bomb attached to a vehicle of the convoy.

The Taliban insurgents fighting Afghan forces and more than 84,000 NATO-led coalition troops recently announced that the cold weather during the harsh winter will not prevent them to attack security forces.

Earlier Saturday, one NATO soldier and six militants were killed when Taliban launched an attack on a military camp in eastern Nangarhar province while a police commander was killed in a sticky bomb explosion in neighbouring Ghazni province.

On December 27 last year, three NATO soldiers were killed when a suicide car bombing hit a military convoy in eastern Kabul.
