Scotland's first minister has described a riot following a United Ireland march in Glasgow as "utterly unacceptable".
Riot police were called onto the streets of Glasgow on Friday evening after the Irish Unity march was met by loyalist protestors.
Mounted officers, a helicopter and dog units were also used to quell the clashes in the Govan district.
The planned march by the James Connolly Republican Flute Band was intended to start at 6.30pm but it was met by a counter demonstration of "several hundred people" from loyalist groups at around 7pm.
Police said this led to "significant disorder", with Govan Road blocked by officers.
Two men, aged 37 and 21, have since been arrested and charged in connection with the incident.
First Minister Nicola Sturgeon described the scenes as "utterly unacceptable".
She said: "Peaceful protest is a part of our democracy - violent and sectarian disruption is not".
Ch Supt Mark Hargreaves said: "Police Scotland has a duty to facilitate processions and any peaceful protest, but this kind of behaviour by persons demonstrating against the parade is utterly unacceptable.
"It is extremely disappointing to see people acting in this fashion, causing fear and alarm to members of the public as well as putting many people at risk."
Glasgow City Council described the events as "unacceptable".
It continued: "The council is clear that the law expects it to facilitate public processions; including those that some people oppose or find offensive.
"However, this cannot continue to be at the expense of the overwhelming majority of Glasgwegians, who want nothing to do with these marches, or counter-protests.
"The city needs and wants fewer marches. We are prepared to consider any action that will protect communities from morons intent on bringing mayhem to the streets of our city".
