Celtic fans have appeared in a clip chanting pro-IRA lyrics at Manchester airport. 

The clip, posted on social media, shows groups of fans chanting in Manchester airport lounge. 

Taken before Celtic's Champions League defeat last night, supporters wearing Celtic strips jump up and down and bang on the walls chanting 'Ooh ah up the'RA'.

Thousands of fans flew out to Munich ahead of the clash against Bayern Munich which saw the Parkhead side defeated 0-3. 

Videos of fans partying in the streets before the game circulated social media yesterday. 

Last month police hunted for two Celtic fans who appeared in a sickening video chanting about Lee Rigby. 

In the 50 second clip, a group of men, some wearing Celtic strips, can be heard clearly singing "f*** Lee Rigby, he won't be f***ing drumming anymore" as they walk down the street.

One man resigned from his job after being identified by police.
