Two singers who performed as part of the 68th Eurovision Song Contest in Malmo, Sweden on Tuesday were reprimanded by event organizers for wearing pro-Palestinian symbols.

Opening act performer Eric Saade wore a kaffiyeh—a headscarf that can be a symbol of Palestinian solidarity—on his wrist during the show Tuesday. And Irish contestant Bambie Thug told reporters that same night that contest organizers “ordered” them to change their stage make-up before their semi-final performance because of its pro-Palestine references, according to BBC.
