An explosion has ripped through the centre of Kosovo's capital Pristina, injuring more than 20 people.
Witnesses at the scene and local television stations say the explosion was caused by a car bomb, but the police said they did not yet know what caused it.
Zeke Zekaj, a doctor on duty in the local hospital, says seven of more than 20 people injured in the blast suffered serious injuries.
UN police and Nato-led peacekeepers cordoned off the area - a part of the city popular with young people in the evenings - and ambulances took the injured to hospital.
Some restaurants and bars near the explosion were heavily damaged. At least two cars were burning in the aftermath.
Kosovo has been administered by the UN since June 1999, when Nato's air war forced former Yugoslav president Slobodan Milosevic to relinquish his control over the province.
Despite the large presence of peacekeepers and police, the province still remains tense.
Tomorrow, a UN Security Council delegation is expected to arrive in Kosovo for a three-day fact-finding visit.
