BELGRADE, Aug 28 (Reuters) - A Serbian nationalist movement says it is trying to establish a nationwide network of "safe houses" for top war crimes fugitive General Ratko Mladic, the Belgrade daily Pravda reported on Tuesday.

Posters and stickers with the words "Safe House for Ratko Mladic" appeared on Monday morning in the capital and seven other towns in central and southern Serbia.

"We plan to print thousands of such signs for citizens to put up on doors and windows, so the general would know which house was a safe hiding place in case, God forbid, someone tries to arrest him," said Misa Vacic, spokesman for the 1389 group.

Mladic, commander of Serb forces in the 1992-95 Bosnia war, has been indicted for genocide by the United Nations war crimes tribunal for former Yugoslavia in The Hague. He is accused of organising the 1995 Srebrenica massacre of 8,000 Muslims and the 43-month siege of Sarajevo.

Serbia's failure to arrest and extradite Mladic to the U.N. war crimes court is a major obstacle to the country's bid for European Union membership.

Vacic said his group, named after the date of the Battle of Kosovo in which the Serbs were defeated by the Ottoman Turks, wanted to show the world that Mladic had the support of Serbs.

"One of our teams was stopped by a police patrol, but instead of filing a report against them, they asked for a poster to put up on the police station wall," he said.
