Rally against Breivik over 'marxist' children's song claim

Some 40,000 people have gathered on an Oslo square to sing a popular peace song which mass killer Anders Behring Breivik condemned at his trial.

The right-wing extremist had accused the singer of Children Of The Rainbow, Lillebjoern Nilsen, of being a Marxist who sought to brainwash children.

Nilsen led the crowd on Thursday in singing the song on Youngstorget Square, close to the courthouse.
