GENEVA (AP) — Organizers of the Eurovision Song Contest said Thursday they reserve the right to remove any Palestinian flags and pro-Palestinian symbols at the show next week in Sweden.

The announcement came amid heightened tensions surrounding Israel’s participation in the annual music competition over its military campaign against Hamas in Gaza, now in its seventh month. Pro-Palestinian groups are expected to stage large protests in Malmo to raise awareness of their cause.

Michelle Roverelli, the head of communications for the European Broadcasting Union that runs the show each year, said ticket buyers are only allowed to bring and display flags that represent countries that take part in the event, as well as the rainbow-colored flag.

The Geneva-based EBU reserves the right “to remove any other flags or symbols, clothing, items and banners being used for the likely purpose of instrumentalizing the TV shows,” she told The Associated Press in a text message.
