, BELGRADE (Reuters) - - Serbian police on Tuesday detained a Kosovo Serb politician who said he was involved in a deadly shootout with Kosovo police 10 days ago and handed him to a Belgrade prosecutor, the country's interior ministry said in a statement. Tensions between Belgrade and Pristina have soared since Sept. 24, when around 30 armed Serbs barricaded themselves in a Serbian Orthodox monastery near the northern Kosovo village of Banjska, resulting in a shootout with Kosovo police.
