Liverpool fans and Rangers 'ultras' clashed inside Ibrox after Jurgen Klopp's side hammered the Light Blues 7-1 on Wednesday night.
Video footage posted on social media shows fans being separated by security inside the stadium as the two groups sang, shouted and gestured towards each other.
Pro-IRA chants of 'up the Ra' can be heard in one clip, which appears to have been taken by Liverpool fans, to goad Rangers supporters who then charge towards the away crowd, reports The Daily Record.

Police and officials are then forced to step in to keep the crowds separated.
In another clip, chants of 'what the f****** hell is that?' and 'Lizzie's in a box' can be heard as Rangers fans are seen shouting and gesturing back to their rivals.
Security staff were later forced to create a human wall down the aisles of the seating area to keep jostling fans apart.
Gers supporters, who had their faces covered with scarves, masks and balaclavas were ushered out of the stadium ahead of Liverpool fans exiting.
One man was arrested and charged with an alleged disorder offence. Along with the single arrest, another was given a warning by officers at the Glasgow fixture, Police Scotland confirmed on Thursday.
A Police Scotland spokeswoman said: "One man, aged 34, was arrested and charged in connection with a minor disorder offence. One man, aged 22, was given a Recorded Police Warning in connection with a minor disorder offence."
Scott Arfield's 17th minute goal sent Ibrox into dreamland and offered hope that their Champions League knock-out hopes wouldn't be dashed with two games to spare.
But they were brought crashing back down to earth just seven minutes later. James Tavernier wasn't strong enough against Roberto Firmino and the Brazilian nodded the Reds level.
Firmino added his and Liverpool's second to turn the game on it's head before Darwin Nunez afforded them a two-goal cushion.
Salah entered the fray and made a point to his manager by making it 4-1, outmuscling Borna Barisic before toe-poking beyond McGregor.
And the Egyptian was at it again for the fifth after Rangers gave the ball away again, taking a touch to create space before whipping the ball past Allan McGregor and in. He wasn’t done there, adding a sixth for his six-minute hat-trick before Harvey Elliott made it seven.
