Palestinian flag is a nightmare for Celtic

They may have won the match against Hapoel Beer Sheva, but their fans let down a good spectacle. In an thrilling game from all ten played this Wednesday Celtic has won the Israeli side 5:2 and now they have to pay the price for its supporters' behavior.
Because of Palestinian flags which was waved on Celtic Park, the Scottish champions will now likely be fined. As around 100 of them were on the stadium, this 'incident' is 'treated' as 'illicit banners' who UEFA explicitly forbids and yesterday the organization confirmed that it has opened disciplinary proceedings. This case will be dealt on 22 September.
It is the second time that Celtic is accused for the same reason after 22 July 2014 when the club played against KR Reykjavik on the same competition - Champions league, but in second qualifying round.
