It was during Noam Bettan's performance of "Michelle" that the television audience heard "stop the genocide" from the crowd, writes SVT.
Four people were removed from the arena as a result.
Israel's involvement has been the subject of extensive debate in recent years, and security measures around the country's performance are extensive. Despite this, the shouts could be heard on the broadcast.
"A person in the audience loudly expressed his opinions about the Israeli artist during his performance, which was heard in the live broadcast. The person was removed for causing a disturbance. Three more people were removed from the arena due to disruptive behavior," the EBU writes in an email to SVT.
