B92 Radio in neighboring Serbia cited reports from news media in Bosnia-Herzegovina that the large demonstrations began this week.
In Sarajevo, the Bosnian capital, demonstrators set fire to the Presidency building and five vehicles parked nearby. In Tuzla, Bosnia's third-largest city, protesters invaded a government building and then left quickly as smoke emerged. Protesters also threw stones at a court building.
Police estimated the crowd in Tuzla at about 3,000 people.
A BBC correspondent in Serbia said Bosnia has been paralyzed by ethnic divisions, with two separate governments. He said the unemployment rate is running at about 40 percent.
