s of "Alternativa" and damaged several apartments before a fire broke out, threatening to spread to adjacent buildings. There were no injuries. It was the second attack in a few weeks on the paper, owned and edited by retired Bosnian Serb army colonel Milovan Stankovic, an open supporter of Bosnian Serb President Biljana Plavsic in her power struggle against ultra-nationalist rivals. The cause of the explosion was not immediately known but it was a sign that the conflict between Western-backed Plavsic and rivals loyal to indicted war criminal Radovan Karadzic will continue despite recent agreements between the two sides. The first attack on Alternativa was on August 28 when an unknown assailant opened fire with an automatic weapon at the journal`s office and threw a hand grenade. The Doboj Socialist Party headquarters were also attacked on that day. Stankovic is a member of the board of the Socialist Party, close to Yugoslav President Slobodan Milosevic`s Socialists in Serbia. Karadzic`s Serb Democratic Party is expected to lose votes in the municipal elections held two weeks ago to two rival Serb parties - the Socialists and the Radical party. Plavsic has used accusations of corruption and profiteering to try to undermine support for Karadzic, the Serbs` wartime leader, and his hardline allies who still wield extensive power in the Serb-controlled part of Bosnia and have obstructed the implementation of the 1995 Dayton peace treaty.
