Serbia has formally asked Britain to extradite ex-Bosnian leader Ejup Ganic and believes its case against him is strong, a Serbian war crimes prosecutor was quoted by AP as saying on Wednesday. The 64-year-old former Bosnian vice president was arrested March 1 at London's Heathrow airport on a Serbian warrant in connection with the 1992 death of Yugoslav army troops in Bosnia. Bosnia has said the Serbian warrant was illegal and that the accusations were political. The British court said it will look into Belgrade's evidence against Ganic and decide whether he should be extradited. In a move of support for Ganic, Bosnian leader Haris Silajdzic, will attend a hearing in London on Thursday. An adviser, Damir Arnaut, said Sarajevo hopes the judge will release Ganic on bail. But Bruno Vekaric, deputy Serbian war crimes prosecutor, said that «our evidence is very strong, we have all the arguments» against Ganic. Vekaric said Serbia accuses Ganic of ordering an attack on retreating soldiers in the Bosnian capital of Sarajevo. The Serbs initially filed an extradition warrant for the deaths of more than 40 people, but Vekaric said the file focuses on the deaths of 18 soldiers and the wounding of 22. «We believe there is enough evidence to hold him responsible for those crimes,» Vekaric said. -- SPA
