Rangers FC and Feyenoord fans hurled chairs at each other in a violent clash after the rival clubs' draw in the Europa League group stage.
Footage shows chairs and other objects being thrown at a Rotterdam hotel where Rangers fans were having drinks in a cocktail bar on Thursday night.
A Rangers fan told the Daily Record that the Feyenoord supporters attacked the Brits just hours after the clubs played out a 2-2 draw.
In the video, supporters of the Dutch side throw chairs against the bar's glass doors and windows and try to goad the Rangers fans into coming outside.
As the Feyenoord fans move back into the street, a number of Rangers supporters rush outside to throw chairs and other objects outside the Hilton hotel.
The violent scenes unfolded at about 11.30pm.
A Rangers fan told the Record: "We were just sitting having a drink in the bar at the front of the hotel when we were attacked.
"It's a cocktail bar and there were a lot of Rangers fans here."
At least 18 people were arrested near Feyenoord's stadium, De Kuip, earlier in the evening, Dutch media reported.
Six were arrested for allegedly failing to comply with an order.
Five were arrested on suspicion of setting off fireworks, two for insulting, one for wanton behaviour, one for public intoxication, two for selling things illegally and one for an undisclosed offence.
Dutch media said only one of those arrested was Scottish. That person was arrested for allegedly being intoxicated in public.
Following the 2-2 draw, Rangers sit atop Group G with eight points, one ahead of Porto and Young Boys.
Feyenoord is at the bottom with five points.
