Celtic have been hit with a fine of more than £10,000 following their latest UEFA charge.
The Scottish champions were punished after fans set off fireworks during their Europa League draw against Fenerbahce in Turkey and for the "improper conduct of the team."
The latter charge is automatically triggered when a team receives five yellow cards in a European match, which happened to Celtic during the 1-1 draw on December 10.
UEFA announced the punishment on Tuesday following a meeting of their control, ethics and disciplinary body.
Celtic have also issued indefinite bans to two supporters following the incidents in Turkey after revealing in December that they were considering legal action against individual fans.
The Scottish club were fined €10,000 for an identical charge sheet following their defeat by Inter Milan in Italy earlier in 2015, and the latest case was the eighth time in five seasons that they have been punished by the European governing body for supporter misconduct.
The Premiership leaders later called for an end to the use of flares among supporters.
A statement read: "Celtic supporters travel in their thousands to European matches and the club is always grateful and proud to have such a magnificent following from fans who have earned a wonderful reputation.
"Backed by our supporters' groups, the club has repeatedly stated its strong opposition to the use of pyrotechnics and took the appropriate action following this match in relation to the individuals concerned.
"Clearly this is something the club and our supporters do not wish to see repeated."
