A UN envoy sent to Ukraine's tense Crimea region, Robert Serry, decided to cut short his mission on March 5 after he was threatened by unidentified gunmen, an assistant traveling with him told AFP. Serry, who was in the Black Sea peninsula to assess the situation for the United Nations, was on his way to the airport immediately after a confrontation with gunmen outside the naval headquarters in Crimea's capital of Simferopol.
