Demonstrators in Bosnia-Hercegovina have set fire to government buildings as violent protests continue across the country for a third day.Police have used rubber bullets and tear gas against protesters in the capital Sarajevo and the northern town of Tuzla.
The protesters are unhappy about economic and political progress in the Balkan country. It is the worst unrest since the end of the Bosnian war.
About 40% of Bosnians are unemployed.
Local media report that demonstrators have tried to get into the presidential building.
Sarajevo-based newspaper Daily Avaz says windows in the building have been broken.
At least 50 people have been injured in the capital, the paper reports.
On Thursday, clashes between police and demonstrators in Tuzla injured more than 130 people, according to Reuters.
The unrest began in Tuzla earlier in the week, with protests over the closure and sale of factories which had employed most of the local population.
Demonstrators in other towns supported the Tuzla workers and criticised the government for failing to tackle rampant unemployment.
The BBC's Balkans correspondent Guy De Launey says exasperation at years of inertia and incompetence in Bosnia is at the root of the protests.
