Show Racism the Red Card call for an end to unacceptable behaviour.
Show Racism the Red Card and Show Bigotry the Red Card today join football leaders, politicians and police in condemning the events that took place at Wednesday's match between Celtic and Rangers.
Scottish Football Association Chief Executive Stewart Regan says the events at the game were "embarrassing".
The SFA is to launch an inquiry after three players were sent off and angry scenes broke out at the final whistle.
"I was saddened and deeply embarrassed to witness the scenes during what's supposed to be Scottish football's flagship fixture," said Regan.
"The SFA condemns the inflammatory and irresponsible behaviour."
Police also made 34 arrests inside the stadium for a variety of sectarian, racial and breach of the peace offences.
More than 229 people were also arrested in the Strathclyde force area for offences the last time Rangers and Celtic met on 20th February in the league. At that game 16 people were arrested within the grounds of Celtic Park for alleged offences of a sectarian nature.
Scotland's First Minister Alex Salmond announced that a summit involving both clubs, the Scottish Government and the police will be held next week to discuss events surrounding recent Old Firm matches.
In a statement, Strathclyde Police confirmed that Chief Constable Stephen House had sought government intervention over disorder issues surrounding the Old Firm fixture.
The statement said: "The Chief Constable has this morning spoken to the first minister (Alex Salmond) regarding the events that have surrounded the Old Firm games this season.
"There can be no doubt that the levels of drunken violence that have blighted our communities and the number of people who have been arrested due to their sectarian behaviour is simply unacceptable. Something has to be done.
Show Bigotry the Red Card was launched in 2009 to tackle sectarian behaviour and religious intolerance in Scottish football and have produced an educational film called ‘Rivals Not Enemies’.
Show Bigotry the Red Card has undertaken a series of debates around the issue of Sectarianism and the next event is due to take place at Scotland's National Stadium, Hampden Park Glasgow on Thursday 24 March 2011.
