UNITED NATIONS (Reuters) - The United Nations voiced concern on Friday about plans by regional authorities in Crimea to hold a referendum on whether to secede from Ukraine and join Russia and warned against decisions being taken "in the heat of the moment."
The east-west confrontation sparked by the overthrow last month of President Viktor Yanukovich after violent protests in Kiev escalated on Thursday when Crimea's parliament, dominated by ethnic Russians, voted to join Russia and called for a March 16 plebiscite on the issue.
