Police in Kosovo say one officer and two protesters have been injured in clashes in the capital, a day after the opposition disrupted parliament with tear gas to protest against agreements with Serbia and Montenegro.

Police said 10 protesters were arrested early Saturday as a few hundred opposition supporters threw petrol bombs and other objects outside the parliament building in Pristina.

After failing twice to hold the parliament session in their chamber on Friday, lawmakers of the two governing political parties moved to a different space in the building to meet — without their opponents.

The opposition had demanded cancellation of Friday's session unless the government renounced deals with Serbia to give more powers to Serb-dominated areas in Kosovo, and with Montenegro on border demarcation.
