The Financial Times reported Wednesday that in a recent interview, U.N. prosecutor Carla del Ponte said the Serbian government has begun to cooperate in a manner that would likely soon lead to the wartime commander's arrest.
"We have had some concrete signs of good co-operation," she said regarding the international manhunt.
Mladic is charged with organizing the July 2005 deaths of more than 7,000 Bosnian Muslims in Srebrenica, a town in Bosnia-Herzegovina.
The U.N. official's comments came in the wake of the arrest of Croatian fugitive Ante Gotovina and renewed talks between the European Union and Serbia.
European Union officials told the Financial Times that until Mladic is taken into custody, the stabilization and association agreement involving the two sides cannot be signed
