A roadside explosion in southern Afghanistan has ripped through a coalition convoy, killing one Romanian soldier and wounding another.

It was not immediately clear if the explosion was from a recently planted device, or the vehicle ran over ordinance from a past conflict.

Earlier reports indicated the blast late Sunday near the city of Kandahar killed an Afghan soldier. But the U.S. military later confirmed the explosion hit a vehicle with Romanian soldiers inside.

In a separate incident Sunday, in the capital, Kabul, a car bomb exploded on a road near a crowded residential area, causing material damage but no injuries.

Interior Ministry spokesman, Lutfullah Mashal, told reporters at the scene, the explosion was the work of the enemies of peace and stability.
