French NATO peacekeeping troops protect the U.N. court compound during clashes in the ethnically divided city of Kosovska Mitrovica March 17, 2008. Serbs attacked a U.N. convoy carrying Serb detainees from a raid in Kosovo on Monday, enabling several detainees to escape, witnesses said. The attack occurred after U.N. police stormed the main U.N. court in the northern flashpoint town of Mitrovica, retaking it from Serbs who had forcibly occupied the building three days earlier. Dozens of Serbs were arrested in the raid. REUTERS/Oleg Popov (KOSOVO)
