Celtic FC has spoken out after its fans were seen waving a political pro-IRA banner during the second half of last night’s European tie at Parkhead against Linfield.

Around an hour after it was reported the club is facing UEFA charges for the second time this week after last night’s win, Celtic FC has now issued a statement condemning fans’ actions.

The club described how any support for a paramilitary or proscribed terrorist organisation “has no place at Celtic Park.”

Celtic added: “[We have] been consistent in condemning such conduct on the very few occasions in the past when it has occurred at Celtic Park.

“It is unfortunate that such a small minority of the crowd at Celtic Park last night behaved in such a way.

“We know the Celtic support will join us in condemning such behaviour.

“Events last night have resulted in charges from UEFA in relation to the paramilitary banners and unsafe behaviour in a section of the Celtic support.

“The club has commenced an inquiry and will take appropriate action.”

The Hoops have been charged with having an illicit banner, a kit infringement, and having blocked stairways.

The case will be dealt with on Friday, July 28.

The developments come Celtic striker Leigh Griffiths was charged on Monday with provoking spectators during the first leg clash in Belfast.

The Scottish champions also faced an improper conduct charge for picking up five cards or more.
