Fan violence caused a stoppage that lasted approximately two minutes during the second half of a Champions League match Wednesday between AS Roma and C.S.K.A. Moscow.
Riot police reportedly stepped in after fans of the Russian club began tossing flares at supporters of the Italian club, which was leading 5-0. Roma eventually won the match 5-1.
As punishment for racist taunting at Champions League match last September, UEFA ruled that CSKA's upcoming home match against Bayern Munich will take place behind closed doors.
