Death threats have been pouring in "every second" since Belgrade signed an EU-brokered agreement to normalize relations with its former province, Kosovo, dpa cited Serbian Deputy Premier Aleksandar Vucic as saying Saturday. "Every second I receive messages that they will kill me," Serbian state television RTS quoted him as saying. He said that his family - a wife and two children - has also been named in the threats. Vucic, whose Progressive Party (SNS) is the largest in parliament, was instrumental in the talks with Kosovo, which ended with a crucial agreement Friday night, details of which still have not been released to the general public. Hailed by most parties in Serbia, the deal was, however, condemned as treason by nationalists. Activists of the far-right Serbian Radical Party on Saturday handed leaflets with Vucic's mobile phone number to people in the streets, according to the report. The agreement with Kosovo, which is expected to be approved by governments in Belgrade and Pristina on Monday, regulates affairs between Serbia and Kosovo for the first time since the territory, which has a mostly Albanian population, declared independence in 2008. The two sides wrangled the most about the level of autonomy, as well as security guarantees for the Serb minority, which dominates the northern section of Kosovo. Vucic and Prime Minister Ivica Dacic insist that the deal was the most Belgrade could secure for its compatriots and that it does not mean that Serbia recognizes Kosovo's independence. The nationalist parties, however, accuse the government of selling Kosovo out to open the door to membership talks with the EU.
