Two Celtic fans have been stabbed in the centre of Rome ahead of tonight’s Europa League match.
It’s thought fans were attacked by a faction of the Lazio support outside Flan O’Brien’s Irish bar in the city centre.
Celtic are due to play Lazio in a Europa League clash at the Stadio Olimpico on Thursday evening.
Tensions were high amid warnings Lazio fans were upset over banners displayed at Celtic Park during their previous meeting in Glasgow last month.
Italian police said the injured pair were taken to hospital for treatment, with one released on Thursday morning.
A 35-year-old is still in hospital with lower abdomen wound.
Liam Graham, a Celtic fan from Glasgow, witnessed the attack, which he described as “totally unprovoked”.
“It was totally unprovoked. Actually can’t believe it, it’s an absolute disgrace,” he told STV News.
“I headed to the bar to meet up my mates when out of nowhere four or five guys started coming towards the Celtic fans sitting outside.
“One of them attacked a guy just sitting enjoying himself and then it all just kicked off. Hopefully the guy is alright but it was terrible.
“Once the police stepped in they fled but it was a total disgrace. We shouldn’t have to fear for our lives on a trip to watch Celtic know what I mean.
“Honestly didn’t know what was going to happen but it was just panic in case me or any of my mates were injured but thankfully not.
” I want to send my best to the guys though, hopefully they’re alright.”
Celtic issued guidance for the 9000 travelling supporters earlier this week amid safety concerns.
Supporters are advised to avoid wearing club colours while walking around Rome, particularly in the evening, stay in large groups where possible and keep a low profile.
A spokesperson for Celtic said: “We can confirm that two fans have been injured after being stabbed last night.
“Both are now in hospital and 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.”
A video has also emerged of Celtic fans being attacked in Rome’s Baccanale bar.
Kevin McGuire posted footage of the bar’s windows being smashed on Wednesday night, stating: “Such a normal bar, not even a Celtic hint about it.
“No singing, no colours. Took us a by complete surprise.”
Police helped to escort the fans to safety.
The Glasgow club and Lazio were charged by Uefa over “illicit chants” heard during their Europa League match on October 24.
Celtic were also charged over the display of an “illicit banner” during the game, which they won 2-1.
