Armed men seized a Ukrainian border checkpoint at a ferry terminal between Russia and Crimea on Monday, Reuters reported, citing Ukrainian border guards.
Russians had been surrounding the ferry terminal for days, but had not taken control of Ukraine's border guard station until now.
The troops seized the checkpoint after guards tried to stop two buses carrying seven armed men, and the next ferry brought three truckloads of soldiers across, a border guard spokesman said, Reuters reported.
Meanwhile, Russian U.N. envoy Vitaly Churkin says ousted Ukrainian President Viktor Yanukovych has sent a letter to Russian President Vladimir Putin, asking him to use military force in Ukraine.
Churkin quoted Yanukovych, who fled to Russia, as saying "the life and security and the rights of people particularly in the southeast part in Crimea are being threatened," and continued: "So under the influence of Western countries there are open acts of terror and violence."
