Kosovo and international authorities expressed regret over the high number of injured in the demonstrations and called for suppressing any form of violence which could undermine the political process in Kosovo.
Nearly 80 persons requested medical help at Pristina's general hospital after the demonstration downtown organised by the Self-Determination movement, which is against UN special envoy Martti Ahtisaari's proposal of gradual independence for Kosovo.
Four seriously injured persons were taken to the military hospital of the NATO-led international peace troops.
After several warnings to the demonstrators not to break a police cordon, the police used tear gas, rubber bullets and truncheons to disperse them. Last night the police arrested 15 persons as well as Self-Determination leader Albin Kurti.
The movement accused the police of violent action, while the Kosovo Committee on the Protection of Human Rights and Freedoms said the force used to disperse the demonstrators had been exaggerated.
Prime Minister Agim Qeku said the right to protest was a democratic right but condemned the escalation of violence in Pristina yesterday. Political parties condemned the violence as well and called for preserving peace in Kosovo.
