Italian KFOR (Kosovo Force) soldiers stand next to banner reading "Stop to EULEX", referring to the European Union Rule of Law Mission in Kosovo, during a rally in the northern part of the ethnically divided Kosovar town of Mitrovica May 21, 2009. Around 1000 Kosovo Serbs protested on Friday against the visit of U.S. Vice President Joe Biden to Kosovo. Biden received a tumultuous welcome in Kosovo on Thursday just hours after leaving Serbia where thousands of police kept streets empty to avoid anti-American protests.
