Kabul  - Two soldiers under NATO command were killed and another was wounded Tuesday in a roadside bombing in south-eastern Afghanistan, the alliance said.

The attack happened in Khost city, the capital of the province of the same name, when a convoy of the NATO-led International Security Assistance Force (ISAF) was coming out of its base in the Sarbagh area.

"The attack killed two soldiers and wounded another," said an ISAF media officer in Kabul who declined to be named.

In accordance with ISAF rules, the media officer did not reveal the nationalities of the soldiers. Most of the forces deployed in the eastern and south-eastern provinces are US soldiers.

No group immediately took responsibility for Tuesday's attack.

Taliban militants, who lost power in a US-led invasion in late 2001, have carried out thousands of roadside bombings in the past seven years.

Around 35,000 US soldiers are part of a 70,000-strong international forces deployed to Afghanistan from 41 nations. The United States has announced a plan to send in up to 30,000 additional troops in the next 12 to 18 months to quell the Taliban-led insurgency in the country. (dpa)
