Police in Slovenia say that 33 people are facing charges for clashing with police during anti-government protests in the capital that left more than 15 people injured, fueling tensions on the eve of a presidential election.

Maja Ciperle Adlesic, a police spokeswoman, said on Saturday that the demonstrators had been released from detention.

Adlesic said the protesters had been charged with violating public order and will face further charges for attacking police at Friday's demonstrations in Ljubljana.

About 8,000 people joined the demonstrations against Prime Minister Janez Jansa's government.

Police say violence erupted at the end of the gathering when about 100 violent extremists threw rocks and police responded with water cannons and tear gas.

Slovenia has been struggling through an economic crisis linked to the eurozone downturn.
