Islamic state terrorists are reportedly planning an attack on this year's Eurovision Song Contest. 

According to the Daily Star, Sweden’s security services are on red alert after terrorists have managed to pass the Stockholm borders ahead of May's Eurovision Song Contest. 

Jesper Ackinger, Eurovision project manager,  said: “We are working closely with the police and have regular meetings.”

Graham Norton is set to host the show, taking place at the Globe Arena which holds an audience of 16,000 fans. 

The Eurovision host is believed to be traveling to Stockholm soon for rehearsals ahead of the May 14 broadcast.

"This is worrying for everyone about to head out there," a BBC insider told the Daily Star.
