Celtic have confirmed that two of the club's fans sustained injuries after being stabbed in Rome on Wednesday night ahead of the Celtic's match against Lazio in the Europa League.
A statement released by the club says: "Celtic can confirm that two fans have been injured after being stabbed last night. Both will receive every support from the club and the British consulate in Rome.
"Again, we would strongly advise supporters to closely follow all guidance issued by the club."
Both men were taken to hospital following the attack but one of them has since been released following treatment. BBC reports that the fans were attacked by masked men outside the Flann O'Brien bar in Rome.
Tensions have been high following the match between the teams in Glasgow two weeks ago, with both clubs charged by Uefa for their fans' illicit chants, while Celtic were also charged for fans unfurling an "illicit banner" during the game.
Speaking about events in Rome last night, BBC Scotland's Chris McLaughlin said:
"In terms of the Flann O'Brien pub, I'm told that around five or six masked men appeared from a side street and started to attack the Celtic fans randomly, for no apparent reason."
Celtic have issued additional guidance for fans in Rome which includes advice such as "Under no circumstances should supporters make their own way to the stadium," and "Avoid wearing club colours whilst walking around the city particularly in the evening."
