Macedonian police have filed criminal charges against 15 people suspected of being involved in a violent attack against the parliament.
Police said the group was charged with "participation in a mob and preventing officials from performing their duties".
Months of political tensions in Macedonia boiled over on Thursday night over disagreements about the election of a new parliament speaker.
More than 100 people were injured, most of them protesters.
Police officers and about a dozen MPs were also injured.
Western diplomats expressed concern on Friday that authorities failed to prevent the attack and did not provide the necessary security for the MPs and journalists present at parliament.
