German rockers Rammstein have rubbished the suggestion their music encourages violence, insisting fans should use it to release aggression.

The terrorists who killed more than 340 after storming a school in Beslan, Chechnya, in September 2004 reportedly listened to the band while they held the school hostage.

But frontman Till Lindemann insists they are not to blame.

He says, "Our music is made to release aggression, and people listening to it are also needed to do that, but it's not our fault. Should we stop making hard music because bad people like it?"
