A member of a European Union policing mission in Kosovo was killed and two others were injured in a roadside ambush in the volatile northern region of the country, where hundreds of American soldiers are among NATO troops watching over a fragile peace. The shooting drew immediate international condemnation. Stars and Stripes said EU foreign minister Catherine Ashton called for a swift response to the attack, in which a pair of vehicles carrying officers with the mission came under gunfire in the northern town of Zvecan. A Lithuanian policeman died and two other officers were injured, according to an EU release. NATO Secretary-General Anders Fogh Rasmussen called the attack \"unacceptable.\" The vehicles carried six police officers returning south from a customs gate on Kosovo’s northern border with Serbia.
