Iran’s national museum has said it will cut all ties with the British Museum in protest at a decision to delay the loan of an ancient Persian treasure.
The Cyrus Cylinder dates back to the 6th Century BC and is regarded as the world’s first declaration of rights.
The British Museum says it needs to keep the artefact until the summer in order to continue its research.
But the head of Iran’s state cultural organisation said the move was unacceptable and politically motivated.
“The Cultural Heritage Organisation has cut all its relations and co-operation with the British Museum,” said the head of the organisation, Hamid Baqaie, according to Reuters news agency.
