Demonstrators in Bosnia-Hercegovina have set fire to government buildings, in the worst unrest since the end of the 1992-95 war.

Hundreds of people have been injured in three days of protests over high unemployment and perceived inability of politicians to improve the situation.

Police used rubber bullets and tear gas to quell unrest in the capital Sarajevo and the northern town of Tuzla.

Black smoke could be seen gushing from the presidency building in Sarajevo.

Sarajevo-based newspaper Dnevni Avaaz says police used water to disperse the protesters who were throwing stones at the presidency building. There were also reports of an attempted storming of the office.
