At least four NATO servicemen were killed in an attack in eastern Afghanistan this morning, the International Security Assistance Force said.

Earlier, Ziaul Rahman Sayedkhili, a senior police officer in the eastern province of Parwan, said the death toll included six NATO soldiers, ten Afghan civilians and two Afghan policemen.

"Two days ago a rocket was fired from the village of Qalandar Khil which hit the Bagram (military) base and this morning a joint Afghan-ISAF operation went there to investigate the case," he said.

"There was a suicide bomber on a bicycle who detonated his explosives which killed ten local civilians, two policemen and six ISAF soldiers."

ISAF said in a separate statement four of its servicemen were killed.

The Taliban claimed responsibility for the attack in a text message to Reuters.             

The attack took place amid deteriorating security in Afghanistan as most ISAF forces prepare to leave the country after 12 years of war against Taliban insurgents.
