Burnley have vowed to 'identify and prosecute' fans involved in tragedy related chanting and gestures against Manchester United, after condemning footage of a supporter appearing to mock the Munich air disaster.
Footage was posted on social media following Burnley's 1-1 draw against Man United on Saturday.
Clarets supporters celebrated Zeki Amdouni equaliser from the penalty spot in the 87th minute at Old Trafford.
One supporter was seen making aeroplane gestures with his arms towards Man United fans and appeared to say the word 'Munich'.
The gesture appears to be in reference to the 1958 Munich Air Disaster, in which 23 people died on their way home from a European match, including many members of the Man United team nicknamed the 'Busby Babes'.
Burnley issued a statement on Saturday night condemning the 'offensive footage', with the club vowing to work with Man United and police to identify and prosecute fans involved.
'We are aware of offensive footage currently circulating on social media from the away end of today’s fixture at Old Trafford,' a Burnley statement read.
'Tragedy related gesturing and chanting is completely unacceptable, and Burnley Football Club take a zero-tolerance approach.
'We will continue to work with Greater Manchester Police, Lancashire Police and Manchester United to help identify and prosecute the individuals responsible.'
Last month, two supporters were arrested on suspicion of tragedy chanting during the FA Cup match between Man United and Liverpool at Old Trafford.
Man United and Liverpool have since joined forces to educate schoolchildren about the impact of the Munich and Hillsborough disasters, with managers Erik ten Hag and Jurgen Klopp calling for an end to tragedy chanting.
Football authorities and police have been attempting a major crackdown on tragedy chanting.
Under guidance from the Crown Prosecution Service, chanting about tragedies can be classed as a criminal offence under the Public Order Act 1986, which outlaws behaviour in public that intentionally causes 'alarm or distress'.
