Hundreds of people crowded into Glasgow’s George Square tonight, with police separating rival supporters of the union and independence.
Officers, some on officers, earlier formed a wall to divide a large number of people waving union flags from a small group of Yes supporters.
There have been reports of flag burning and flares being set off.
A number of people draped in union flags later left the area and began spreading on to the nearby streets, with many marching down St Vincent Place as police followed.
Union supporters and people sporting Yes badges argued over the referendum result and a chorus of Rule Britannia was countered by the Scottish anthem, Flower of Scotland.
Roads around the square were closed as police dealt with the incident.
The crowd has gathered opposite Queen Street railway station, which is understood to have shut its doors.

Deeply saddened by the actions on Glasgow. It's given this referendum a bad name.

I am actually embarrassed to say I live in Glasgow. You can't protest over the result forever, it's not going to change.
