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 and fueled tensions on the eve of a presidential election.

Spokeswoman Maja Ciperle Adlesic said Saturday that the demonstrators have been released from detention. She says they have been charged with violating public order and will face further charges for attacking police at Friday's demonstrations.

About 8,000 people joined the demonstrations in Ljubljana against Prime Minister Janez Jansa's government. Police say violence erupted at the end of the gathering when some 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.
