A powerful blast rocked the offices of a Serbian bank in southern Kosovo late Tuesday, officials said. No one was injured. The explosion took place in the ethnically mixed town of Dragas, in the mountainous region bordering Macedonia, and targeted the only Serbian bank allowed to operate in Kosovo by the United Nations mission that runs the province, said police spokesman Veton Elshani. Police said the blast ripped through the bank's offices, shattering windows and causing considerable damage to the building's structure. The area where the explosion happened is inhabited by a Serbian-speaking Muslim community that shuns Kosovo's authorities and mostly follows instructions from Belgrade.
