Foreign ministers from central Europe, the Baltics and Nordics condemned on Friday Russia's military intervention in Ukraine and a planned referendum planned by Crimea's government, calling for the EU to send an observation mission to Kiev. The group of countries, many of them sharing land borders with Russia or the Ukraine and living with the memory of Soviet rule, have taken a tough line in the face of Moscow as the crisis has escalated. "Nordic and Baltic countries and the Visegrad countries' foreign ministers condemned today ... the attack on Ukraine's sovereignty and territorial integrity, and also condemned the illegal referendum on the joining of Crimea with Russia," the ministers said in joint statement from the meeting.
