Kosovo's new president, Hashim Thaci, has assumed his post in a swearing-in ceremony at the Parliament that the opposition boycotted.

Thaci, 47, who replaces Atifete Jahjaga, was elected in Parliament on Feb. 26 in the absence of nearly all opposition lawmakers who earlier tried to disrupt the voting with tear gas.

Earlier this week the Constitutional Court turned down an opposition request to void Thaci's election, saying it had found no evidence of irregularities.

Posters against his election were put up by the opposition in many cities.

The opposition has been disrupting the chamber since last September to protest a deal between Kosovo and Serbia that gives more powers to ethnic Serbs in Kosovo and another on a border demarcation pact with Montenegro.

The ceremony was held Thursday.
