AlQa'dah 20, 1432, Oct 18, 2011, SPA -- The commander of NATO-led peacekeepers in Kosovo said Tuesday he is disappointed by the Serb refusal to remove roadblocks in the north of the country and warned of action if the blockade is not lifted soon. Serbs defied a Tuesday deadline to remove the barriers and gathered by the hundreds to protect them from removal by the peacekeeping troops. Two NATO troop supply convoys were stopped by the Serbs manning the barricades on Tuesday, AP reported. For nearly three months, Kosovo Serbs have been blocking main roads to stop Kosovo's ethnic Albanian leadership from extending their control over the Serb-run territory. Serbs reject Kosovo's 2008 declaration of independence from Serbia. The 5,500-strong peacekeeping force, known as KFOR, had requested that the 16 barriers of rocks, mud and logs be taken down by early Tuesday. -- SPA
