control of the two administrative border posts. However, some roadblocks, set up by hundreds of Serb protesters, prevented them from returning to their bases. The column of American and Slovenian 30 armoured vehicles then withdrew from the barricade, even though they were given permission to move against the protesters using force, if necessary. The decision was made to avoid further bloodshed. On 31 July, the Serbs continued to man their roadblocks and KFOR soldiers remained isolated at the administrative border crossings they were manning. The Kosovars then organised burnings of Serbian products and General Buhler sent an ultimatum to the Serbs blocking the road. On 1 August, NATO said that Swiss Army sappers, supported by other KFOR troops had cleared three of the roadblocks but claimed that there were still at least five remaining on the two roads leading to Serbia. Kosovar interior minister Bajram Rexhepi ordered Serbia's Minister for Kosovo and Metohija, Goran Bogdanović, and the head of the Serbian negotiation team, Borislav Stefanović, to be deported after allegedly having entered Kosovo illegally. The next day, however, some roadblocks remained in place with all major roads being completely sealed off. Agence France Press reported a severe food crisis and a shortage of medicines in the North. KFOR then asked a battalion of 550 German soldiers, assisted by 150 Austrian troops, to reinforce its presence in the north to deal with future unrest. On 3 August, Kosovar prime minister Hashim Thaçi reiterated a refusal to back down on his trade ban as some roadblocks remained in place across the North. A deal was later struck to allow KFOR to control the administrative border crossings in return for the dismantling of the blockades. KFOR helicopters were then used to bypass the roadblocks and establish a skeletal EULEX and Kosovo Police and Customs presence at the administrative border crossings. September–December Tensions reignited after the Kosovo Police, EULEX and NATO units airlifted troops from Kosovo-proper to the two administrative border posts to re-establish control over the North on 16 September. Local Serbs blocked all major routes leading to the two administrative border crossings, including two major bridges connecting the divided town of Mitrovica and vowed to remain "until the bitter end". This left the troops at the administrative border crossings virtually isolated from the rest of Kosovo. European media reported that youths from both the Albanian and Serbian communities pelted each other with
