Serbian police have stopped hundreds of ex-army reservists from going to the border with Kosovo. Former Serb fighters from the Kosovo war planned to remove a border sign saying "Republic of Kosovo" at the Merdare border crossing. But hundreds of police blocked the reservists from leaving the town of Kursumlija. Police scuffled with the protesters but there were no serious incidents. The demonstrators are dispersing but have pledged to come back again on Monday. The Serbs are angry over the Feb. 17 declaration of independence by Kosovo's ethnic Albanian leadership.
