Celtic handed £9500 UEFA fine over misconduct at Inter Milan clash
The Scottish champions were found guilty over two misconduct charges.
Celtic have been fined a total of €13,000 (£9495) over two charges of misconduct at their UEFA Europa League clash with Inter Milan.
Celtic were handed €8000 for the improper conduct of the team as well as a €5000 punishment over two flares set off at the San Siro on February 26.
The governing body's control and disciplinary committee have hit the Scottish champions for the seventh time in just over three years for incidents involving their fans in European competition.
Virgil van Dijk was sent off in the first half for two bookable offences. Craig Gordon, Adam Matthews, Emilio Izaguirre and Nir Bitton were shown yellow, with Kris Commons also being booked after full-time.
Celtic have been charged seven times by UEFA in just over three years because of the conduct of their supporters in European competition.
The club issued a statement saying: "Clearly Celtic Football Club is disappointed by today's decisions.
"It should be noted that Celtic players have an excellent disciplinary record in European football over many years and in Scotland, Celtic has been top of the League's disciplinary table for the last three years, something which we are rightly proud of.
"Again, it is disappointing that the actions of one or two individuals within a support of well over 3,000, have let the club down by using flares at this match.
"Inter Milan and the local Italian authorities applauded our fans for their excellent conduct and positive support. Once again, however, the actions of these individuals have done nothing but damage the club they claim to support.
"Our fans have earned a wonderful reputation for their magnificent support of the club and we will not allow the safety of our fans, or their great reputation to be compromised by actions of this tiny minority."
The club were fined €10,000 following crowd disturbances at their Europa League match with Dinamo Zagreb last year.
An "illicit banner" displayed at a UEFA Champions League qualifier with KR Reykjavik in 2014 drew a £16,000 fine from the governing body.
The club were also handed a £42,000 fine in 2013 for another "illicit banner" at a Champions League match with AC Milan in 2013.
At the time, Celtic chief executive Peter Lawwell condemned the "small minority" of supporters who were "damaging the reputation" of the club.
Earlier in 2013, the setting off of fireworks at a Champions League qualifier with Cliftonville also resulted in a fine of just over £4000.
The club's fans also caused them to be fined twice during their Europa League campaign in the 2011/12 season.
In March 2012, UEFA fined Celtic £21,000 after supporters displayed an offensive banner and set off flares during an away game with Udinese.
Celtic were also fined £13,000 for "illicit chanting" in the same competition during a match with Rennes in 2011.
Inter Milan were also fined €5000 for setting off fireworks during the game.
