A visit to Iran by a European Parliament delegation has been called off after Tehran refused to let them visit two jailed activists recently awarded an EU human rights prize.

Lawyer Nasrin Sotoudeh and filmmaker Jafar Panahi were named joint winners of the Sakharov prize on Friday.

The five EU politicians had been due to arrive on Saturday and wanted to present the award to the activists.

But Iranian media said Tehran could not accept that as a pre-condition.
