A European Union official says participation in Kosovo's first general poll since its independence from Serbia was encouraging, but warned of allegations of fraud.
Doris Pack, a Parliament member who waas an election observer, praised on Monday "increased participation" among ethnic Serbs living in enclaves dotting Kosovo.
But, Pack is urging authorities to take measures against election officials suspected of rigging the vote in at least two of Kosovo's 37 municipalities.
She says observers were alerted to possible "serious fraud" in two regions known as strongholds of Prime Minister Hashim Thaci's Democratic Party of Kosovo.
An unofficial exit poll says Thaci won 31 percent of Sunday's vote. First official results are expected on Monday.
