Italian Carabinieri are seen at a checkpoint set up near the main bridge linking the Serbian and the Albanian part of the ethnically divided town of Kosovska Mitrovica, Kosovo, Friday, Sept. 16, 2011. An EU spokesman in Kosovo says helicopters are being used to ferry staff and supplies to border crossings after minority Serbs blocked main roads to the tense areas. The EU action seeks to reopen trade between Kosovo and Serbia following a border dispute in July. (AP Photo/Visar Kryeziu)
