Violent scenes broke out in Glasgow on Friday night as a large number of police were forced to maintain peace in a city that only yesterday voted for independence.
Hundreds of individuals waving union flags and chanting anti-independence slogans descended on George Square, where police struggled to contain them.
George Square was the focus for Glasgow's Yes Scotland campaigners in the run-up to and during Thursday's referendum, and hosted regular gatherings for pro-independence supporters.
The situation on Friday was tense, as the pro-union section of the crowd chanted "Rule Britannia".
fight breaks out. Whole square runs over chanting and shouting and singing Rule Britannia. Nasty business. And not about referendum.
Some Yes voters in the square were separated from the unionist group by police.

Red smoke bombs flew over police lines outside Glasgow Queen Street railway station.
But police just about kept the the area under control after deploying substantial numbers of officers and mounted police.
The disturbance then spread on to nearby Buchanan Street, one of Glasgow's main shopping districts. Although many of the pro-union individuals appeared to be looking for a fight, there were few Yes supporters for them to attack.
At 10pm on Friday night police horses were working hard to keep the sides apart but largely succeeding.
Six people were eventually arrested, ITV News reported.
