Kosovo police said officers met resistance in Mitrovica as they carried out an operation to seize smuggled goods Police responded when protesters in Mitrovica used hand grenades and stun grenades against officers PRISTINA: One Serb was shot and six police officers injured on Wednesday when police fired tear gas to disperse a crowd. The crowd became hostile after raids on suspected smugglers in a volatile area of Kosovo populated by the Serb minority. Kosovo police said officers met resistance in Mitrovica as they carried out an operation to seize smuggled goods in several towns on Wednesday. A statement said police responded when protesters in Mitrovica used hand grenades and stun grenades against officers. It said six police officers were injured. Serbian state TV showed people running from tear gas and one vehicle set on fire. It said several people were injured. Similar clashes were reported in the nearby town of Zvecan. The European Union’s foreign policy chief Joseph Borrell called for an immediate end to violence in Kosovo’s north, adding that all “open issues must be addressed through the EU-facilitated dialogue” between Belgrade and Pristina. “Unilateral and uncoordinated actions that endanger stability are unacceptable,” Borell said on his twitter account. Belgrade and Pristina agreed to an EU-sponsored dialogue in 2013, but little progress has been made. The Kosovo Online news portal quoted Zlatan Elek, the head of a hospital in Mitrovica, as saying one person was seriously injured. “The injury to the shoulder blade and ribs has been caused by a firearm ... He is in intensive care and is in serious condition,” Elek was quoted as saying. Serbian President Aleksandar Vucic left Belgrade to go to the central Serbian town of Raska to meet representatives of Kosovo Serbs later in the afternoon, his office said. Serbian Prime Minister Ana Brnabic urged NATO, which has 3,000 peacekeepers in Kosovo, to step in and stop the violence. Kosovo’s Prime Minister Albin Kurti said: “Crime and criminal groups will not be tolerated and will be fought. We will fight and stop the smuggling.” Kosovo declared independence from Serbia in 2008, but around 50,000 Serbs who remain in the northern part of the country refuse to recognize the Pristina authorities and see Belgrade as their capital.
