Crimea invites OSCE observers for referendum on joining Russia - RIA

MOSCOW (Reuters) - Ukraine's Crimea region has invited the Organization for Security and Cooperation in Europe (OSCE) to send a mission to observe Sunday's referendum on joining Russia, Russia's RIA news agency said on Monday.

It said the invitation had been issued to the Vienna-based security and human rights organisation by the region's pro-Russian parliament. OSCE military observers have been unable to enter Crimea, which is controlled by Russian forces.
