According to NATO officials six American soldiers and three Afghan soldiers were killed by Taliban fighters in eastern Afghanistan on Friday.

Their patrol was ambushed by the insurgents in Waygal district as the troops were returning on foot from a meeting they had with the village elders.

The ambush occurred in the Nuristan Province, where United States forces are participating in a NATO mission.

Lt. Col. David Acceta, spokesman for International Security Assistance Force said: “It was a complex ambush by machine guns and rocket-propelled grenades that were fired from at least two different positions,” the New York Times reports.

They’ve answered the insurgent attack with machine guns, mortars, artillery and small arms.

According to the statement issued on Saturday eight American soldiers and 11 Afghan soldiers were also injured during the clash. The wounded were transported to ISAF medical facilities in different locations in eastern Afghanistan.

This attack was the deadliest one in Afghansitan for the American soldiers since the Chinook helicopter crashed in February in southern Zabul Province killing eight Americans.

On Saturday a suicide bomber attacked a convoy of NATO-led German troops by detonating his vehicle in northern Kunduz province.

According to  Engineer Mohammad Omar, provincial police chief: “The suicide bomber, who was following a convoy of German forces and was some 40 metres from the convoy, detonated his car, killing himself and wounding an intelligence agent and a passer-by civilian,” Deutsche Presse-Agentur reports. Apparently the injured civilian died due to his wounds.

No one from the German military convoy suffered any injuries. The attacker was identified as a Pakistani national.

The attack was claimed by the Taliban militants on their website saying that it was carried out by a resident of the Kunduz Province, Mujahid Obaidullah, and that eight German soldiers were killed and that one civilian was killed when the forces opened fire after the blast.

More than 130 suicide attacks have been carried out this year by Taliban militants, making this year the most violent since 2001.
