Kosovo’s Central Electoral Commission on March 9 approved referendums in four Serbian-majority municipalities to be held on April 21 on whether to oust their ethnic-Albanian mayors whose election last year raised tensions between Serbia and Kosovo. The commission's decision passed with an 8-2 vote and two abstentions. The commission also confirmed a petition held in January in which about one-fourth of around 45,000 eligible voters in four municipalities in northern Kosovo -- North Mitrovica, Zvecan, Zubin Potok, and Leposavic -- where most of Kosovo’s ethnic Serbian minority lives, were in favor of the new vote. At least 20 percent of eligible voters was needed.
