Bosnian Serb authorities have frozen the bank accounts of 33 people accused of aiding fugitive war crimes suspects Radovan Karadzic and Ratko Mladic.

Local news media reports say those penalized by the Bosnian Serb banking agency include former top Serb Republic officials. The reports named former president Mirko Sarovic, its defense minister, Bogdan Subotic, and former finance minister Milenko Vracar.

The reports say the freeze also was extended to companies owned by the accused. Those firms are said to employ a number of formerly high-ranking officials of the Bosnian Serb Interior Ministry.

The Hague-based United Nations war crimes tribunal is still seeking four Serb fugitives accused of atrocities during the Balkan conflicts of the 1990s.

The two most-wanted fugitives - Karadzic and Mladic - face genocide charges in the 1995 massacre of an estimated 8,000 Muslim men and boys captured in the Srebrenica enclave of eastern Bosnia-Herzegovina.
