NYON, Switzerland (AP) — UEFA has charged Celtic over fans displaying dozens of Palestinian flags at a Champions League game against an Israeli opponent.

UEFA says its disciplinary committee will judge a case of "illicit banners" on Sept. 22. The Scottish champion is likely to be fined.

Political banners and protests are prohibited in stadiums at matches organized by UEFA.

The flags were displayed mostly in one corner of Celtic's stadium during a 5-2 win against Hapoel Beer Sheva in a playoff round, first-leg match on Wednesday.

The return match is in Israel on Tuesday, with the winner advancing to the elite 32-team group stage.

Celtic fans often display some Palestinian flags at domestic and European matches, though many more were seen for Hapoel Beer Sheva's visit.
