Bjork has cancelled the last three concerts of her European tour because of an unspecified "scheduling conflict", organisers said Wednesday.

The Icelandic singer was pulling out of shows she was meant to have performed at two French music festivals and one in Iceland.

"Bjork really wanted to do these concerts", according to her agent, but had to cancel because of "a scheduling conflict outside her control", organisers said.

The agent did not elaborate but said the singer was looking at playing later dates to make up for the ones scrapped.

The news was a blow to one French festival taking place this month, la Route du Rock in the northwestern town of Saint-Malo. It was partially reimbursing people who held tickets for Bjork's August 15 show.

The other two festivals, Pitchfork in Paris and Iceland Airwaves in Reykjavik, said they would fully reimburse tickets for Bjork concerts that were to have been put on in late October and early November.

The three cancelled shows were to cap a mini-European tour that had already taken Bjork to Britain, Slovakia, the Czech Republic, Spain and Germany.
