Gun scare during live broadcast at Cannes Film Festival

A live outdoor television broadcast from the Cannes Film Festival was briefly interrupted when what sounded like gunfire sent the crew and audience running for cover.

Actors Christoph Waltz and Daniel Auteuil were among guests being interviewed on the programme 'Le Grand Journal' when what sounded like gunfire rang out.

Television footage shows Auteuil and Academy Award winner Waltz - a member of the Cannes festival jury - scrambling from the seaside stage with dozens of others as a someone was heard saying "there's someone shooting."

When Friday's programme carried on a few minutes minutes later, host Michel Denisot said the noise had been caused by blank rounds. There were no reports of injuries.

A man was detained by police with a starter's pistol, a pocket knife and a plastic grenade.
