Rangers fans clashed with security staff in Bucharest
Rangers have been fined £18,000 by Uefa following fan violence during their Champions League match against Unirea Urziceni on 4 November in Romania.
And the Romanians have been fined £7,200 for lack of organisation at the same Group G match.
The decision by Uefa's control and disciplinary body follows an investigation launched after Rangers fans clashed with stewards.
Rangers chief executive Martin Bain said they would not appeal the ruling.
And he repeated his condemnation of a section of the Scottish champions' support.
"It is extremely disappointing for both Rangers and the overwhelming majority of our supporters to see the club receive a fine of £18,000 from Uefa and suffer the consequences of the actions of those who took part in the disorder in Bucharest," he told his club website.
"The moronic conduct of these individuals was wholly unacceptable and flies in the face of what we stand for as a football club.
Apart from this incident, the behaviour of the majority of Rangers supporters in Bucharest was satisfactory

"It is particularly frustrating in view of the fact that many people at this club work very hard to ensure supporters travelling to support the team abroad are safe and can enjoy the occasion.
"Our official supporters groups have also tried to encourage sporting behaviour by all fans. However, their efforts are undermined by people who call themselves Rangers fans but have only their own mindless interests at heart. We do not want these people at our matches.
"We appreciate the fact that the Uefa match delegate said in his report that, apart from this incident, the behaviour of the majority of Rangers supporters in Bucharest was satisfactory."
Immediately after the trouble, Bain and Superintendant Mike Dean of Strathclyde Police both insisted there had been poor organisation at the stadium and that Romanian security officials and police treated the Scottish fans heavy-handedly.
"The club made strong representations to Uefa regarding the wholly unsatisfactory crowd management prior to the match and Uefa has addressed this," said Bain in response to the fine for Unirea.
"As we have made clear, this in no way excuses the violent behaviour of some fans.
"At Ibrox, we put a great deal of effort into ensuring a safe environment for spectators and have been complimented by various football authorities and visiting clubs for the arrangements we put in place.
"It is not unreasonable to expect that adequate safety arrangements are in place when clubs such as ours travel abroad. Regrettably, this was not the case in Romania.
"Many of our fans who travel regularly with the club and were not involved in the disorder last week described conditions and their treatment at the stadium as the worst they have experienced in Europe and this led to a very hostile and tense environment outside and inside the ground."
Bain said that he would discuss issues arising from the fine with supporters' representatives.
The Glasgow club could have faced a larger penalty after being fined in recent seasons for fan behaviour during European ties in Villarreal and Pamplona.
Uefa's director of communications Rob Faulkner had told BBC Scotland that incidents over the past five years would come into consideration when the case was examined.
The Glasgow club were fined £13,300 for supporters' discriminatory chanting and £9,000 for attacking their opponents' team bus during an away game against Villarreal in 2006.
The following year, they were fined £8,280 on an improper conduct charge for fans' behaviour at an away Uefa Cup game against Osasuna.
In addition, rioting by fans during last year's Uefa Cup final in Manchester is regarded as one of the most shameful episodes in the club's recent history.
