BELGRADE, Serbia (AP) — Tensions between Serbia and Kosovo flared anew during the past week after Serbs erected barricades on the main roads in the north of the former Serbian province to protest the arrest of a former Kosovo Serb police officer. Shots were fired from the barricades, and a Kosovo Albanian police officer was injured. Serbia raised its combat readiness and warned it would not stand by if Serbs in Kosovo are attacked. Serbian President Aleksandar Vucic has called for deploying Serb troops to northern Kosovo, further fueling fears of a revival of the 1998-99 war in Kosovo that claimed more than 10,000 lives and left over 1 million homeless.
