BUDAPEST, May 29 (Reuter) - NATO's parliamentary wing passed a resolution on Monday requesting the U.N. Security Council to strengthen the mandate of international peacekeepers in Bosnia after Serbs detained over 300 U.N. soldiers as human shields. The North Atlantic Assembly said the Serb's actions required a change in the U.N. mandate, which serves as the framework for its actions in the war-torn former Yugoslav republic. NAA "requests that the United Nations Security Council amended the mendate of UNPROFOR (United Nations Protection Force) so that it is able to respond to any agression to which it is subjected," the resolution said. Only two parlamentarians, from Germany's Social Democratic and Green parties, voted against the resolution, which did not indicate how the mandate should be changed. On Saturday the NAA, which groups legislators from 16 NATO members and 15 Central and East European states, passed a resolution condemning Bosnian Serb actions. The assembly is holding a four-day meeting in the H

ungarian capital that began on Friday. The UNPROFOR mandate now sets the rules of engagement for U.N. soldiers and calls for the force to protect Bosnian government enclaves.
