Nato said today that two of its soldiers were killed in a suicide car bomb attack in eastern Afghanistan.
Nato says the bomb attack in the city of Jalalabad also wounded four soldiers from its International Security Assistance Force. The majority of Nato troops in the region are American.
The suicide car bomber rammed his car into a moving military convoy in the city of Jalalabad before detonating explosives, the governor of Nangarhar province, said.
Three civilians were also wounded.
The Taliban have vowed to step up their campaign of suicide bombings this year, after carrying out 140 such attacks in 2007 that killed 200 civilians.
The al-Qaeda-backed Taliban largely rely on suicide attacks and roadside bomb attacks as part of their insurgency against the pro-Western Afghan government and the more than 60,000 foreign troops in the country.
