Nyon - UEFA has fined Napoli and Trabzonspor a total of €100 000 after fans caused fires in the stands during a Europa League match.
Small fires were started at Napoli's San Paolo Stadium by fans throwing lit fireworks during the Round of 32 match on February 26.
UEFA says its disciplinary panel ordered Napoli to pay €60,000 and Trabzonspor €40,000.
UEFA President Michel Platini this week called for longer stadium bans to help curb fans as hooligan incidents increase across Europe.
Napoli advanced to the Round of 16.
The Italian club plays Wolfsburg next month in the quarterfinals.
