Russian forces tightened their grip on Crimea on Sunday despite a U.S. warning to Moscow that annexing the southern Ukrainian region would close the door to diplomacy in a tense East-West standoff.
Russian forces' seizure of the Black Sea peninsula has been bloodless but tensions are mounting following the decision by pro-Russian groups that have taken over the regional parliament to make Crimea part of Russia.
The operation to seize Crimea began within days of Ukraine's pro-Russian President Viktor Yanukovich's flight from the country last month. Yanukovich was toppled after three months of demonstrations against a decision to spurn a free trade deal with the European Union for closer ties with Russia.
In the latest armed action, Russians took over a Ukrainian border post on the western edge of Crimea at around 6 a.m. (0400) GMT, trapping about 30 personnel inside, a border guard spokesman said.
The spokesman, Oleh Slobodyan, said Russian forces now controlled 11 border guard posts across Crimea, a former Russian territory that is home to Russia's Black Sea fleet and has an ethnic Russian majority.
"I am going to the United states to hold top-level meetings on resolving the situation unfolding in our bilateral and multilateral relations," Yatseniuk said at the start of a government meeting in the Ukrainian capital, Kiev.
President Vladimir Putin declared a week ago that Russia had the right to invade Ukraine to protect Russian citizens, and his parliament has voted to change the law to make it easier to annex territory inhabited by Russian speakers.
The worst face-off with Moscow since the Cold War has left the West scrambling for a response, especially since the region's pro-Russia leadership declared Crimea part of Russia last week and announced a March 16 referendum to confirm it.
"He made clear that continued military escalation and provocation in Crimea or elsewhere in Ukraine, along with steps to annex Crimea to Russia, would close any available space for diplomacy, and he urged utmost restraint," a U.S. official said.
President Barack Obama spoke by phone on Saturday to the leaders of France, Britain and Italy and three ex-Soviet Baltic states that have joined NATO. He assured Latvia, Lithuania and Estonia, which have their own ethnic Russian populations, that the Western military alliance would protect them if necessary.
A spokeswoman for the Organization for Security and Cooperation in Europe said military monitors from the pan-Europe watchdog had on Saturday been prevented for the third time in as many days from entering Crimea.
Shots were fired on Saturday to turn back the mission of more than 40 unarmed observers, who have been invited by Kiev but lack permission from Crimea's pro-Russian authorities to cross the isthmus to the peninsula. No on was hurt.
Crimea's pro-Moscow authorities have ordered all remaining Ukrainian troop detachments in the province to disarm and surrender, but at several locations they have refused to yield.
Moscow denies that the Russian-speaking troops in Crimea are under its command, an assertion Washington dismisses as "Putin's fiction". Although they wear no insignia, the troops drive vehicles with Russian military plates.
A Reuters reporting team filmed a convoy of hundreds of Russian troops in about 50 trucks, accompanied by armoured vehicles and ambulances, which pulled into a military base north of Simferopol in broad daylight on Saturday.
The military standoff has remained bloodless, but troops on both sides spoke of increased agitation.
"The situation is changed. Tensions are much higher now. You have to go. You can't film here," said a Russian soldier carrying a heavy machine gun, his face covered except for his eyes, at a Ukrainian navy base in Novoozernoye.
A source in Ukraine's defence ministry said it was mobilising some of its military hardware for a planned exercise, Interfax news agency reported. Ukraine's military, with barely 130,000 troops, would be no match for Russia's. So far Kiev has held back from any action that might provoke a response.
The United States has announced sanctions against individuals it accuses of interfering with Ukrainian territorial integrity, although it has yet to publish the list. Washington has threatened wider action to isolate the Russian economy.
The European Union is also considering sanctions, but has so far been more cautious. Any action would be much harder to organise for a 28-nation bloc that takes decisions unanimously and many of whose members depend on Russian natural gas.
Western countries dismiss the planned referendum as illegal and likely to be falsified.Last Mod: 09 Mart 2014, 13:45
