Animal rights activists protest Rolling Stones gig

The Rolling Stones' will rock Belgrade this summer even if their planned performance at the city's main racetrack stresses hundreds of horses stabled at the venue and means some need to be tranquillised, concert organisers admitted today.

Animal rights group Orca warned against "inevitable stress that the animals would suffer" from the noise, or from diazepam, the substance already used in the past to sedate the animals during concerts.
