SEVASTOPOL/MOSCOW  - Pro-Russian forces seized two Crimean navy bases and captured Ukraine’s naval chief on Wednesday as Moscow tightened its grip on the flashpoint peninsula despite Western warnings its “annexation” would not go unpunished.
Dozens of despondent Ukrainian soldiers – one of them in tears – filed out of the Ukraine’s main navy headquarters in the historic Black Sea port city of Sevastopol after it was stormed by hundreds of pro-Kremlin protesters and masked Russian troops.
“We have been temporarily disbanded,” a Ukrainian lieutenant who identified himself only as Vlad told AFP.
A Russian forces’ representative said that Ukraine’s navy commander Sergiy Gayduk – appointed after his predecessor switched allegiance in favour of Crimea’s pro-Kremlin authorities at the start of the month – had been detained.
A regional prosecutor’s statement said Gayduk was suspected of “ordering Ukrainian military units to open fire on peaceful civilians”.
Defence ministry officials said Russian forces also seized a military base in Crimea’s western port town of Novoozerne after using a tractor to ram open its main gate. An AFP reporter saw about 50 Ukrainian servicemen file out of the base under the watchful eye of Russian soldiers while pro-Moscow militias lowered the Ukrainian flag.
The United States warned Moscow it was on a “dark path” to isolation on Wednesday after Russian troops backed by unarmed volunteers stormed Ukraine’s naval headquarters in the Crimean port of Sevastopol and raised their flag.
“As long as Russia continues on this dark path, they will face increasing political and economic isolation,” said US Vice President Joe Biden, referring to reports of armed attacks against Ukrainian military personnel in Crimea.
Biden was in the Lithuanian capital Vilnius, part of a quick trip to reassure Baltic allies worried about what an emboldened, aggressive Russiamight mean for their nations. Lithuania, along with Estonia and Latvia, are Nato members.
US Vice President Joe Biden on Wednesday said Washington could send forces to the Baltic states to reassure ex-Soviet Nato allies rattled by Russia’s takeover of Crimea.
“We are exploring a number of additional steps to increase the pace and scope of our military cooperation, including rotating US forces in the Baltic region to conduct ground and naval exercises and training missions,” Biden said during a visit to Lithuania, after a first stop in Poland.
 The United Nations said Secretary General Ban Ki-Moon will push for a peaceful solution to the crisis when he meets Putin in Moscow on Thursday and when he travels to Kiev on Friday.
Meanwhile, Ukraine’s acting president on Wednesday said Crimea’s separatist leaders had three hours to release the detained head of the ex-Soviet state’s navy or face “an adequate response”.
Acting president Oleksandr Turchynov said in a statement that “unless Admiral (Sergiy) Gayduk and all the other hostages– both military and civilian ones — are released, the authorities will carry out an adequate response of a technical and technological nature.”
Nato Secretary-General Anders Fogh Rasmussen accused Russia on Wednesday of tossing out international rules in an attempt to “redraw the map of Europe,” as he called the Ukraine crisis Nato ‘s most pressing security challenge.
“We have seen Russia rip up the international rule book, trying to redraw the map of Europe, and creating, in just a few weeks, the most serious security crisis since the end of the Cold War,” Rasmussen told a forum at Georgetown University during a trip to Washington.
Meanwhile, Venezuelan President Nicolas Maduro has criticised US and EU sanctions against his ally Russia for absorbing Crimea. “It is way out of line to threaten with sanctions when these issues must be resolved through the diplomatic channels of international law,” Maduro said on his daily radio program. “They want to surround Russia to weaken it, to crush it, to destroy it,” said Maduro.

A few hundred metres away, the local authorities attached new, Russian letters spelling “State Council of the Crimean Republic” on the building of the local assembly. Putin said his move to annex Crimea was justified by “fascists” in Kiev who overthrew pro-Moscow president Viktor Yanukovich after deadly street protests last month. Ukraine and Western governments have dismissed the referendum as a sham, and say there is no justification for Putin’s actions.

Russian lawmakers raced to ratify a treaty making the Ukrainian region part of Russia by the end of the week, despite threats of further sanctions from Washington and Brussels. The Russian military moved swiftly to neutralise any threat of armed resistance in Crimea. “This morning they stormed the compound. They cut the gates open, but I heard no shooting,” said Oleksander Balanyuk, a captain in thenavy, walking out of the compound in his uniform and carrying his belongings.
 Russia sent thousands of soldiers to Crimea in the buildup to a weekend referendum in which the Russian-majority region voted overwhelmingly to leave Ukraine and join Moscow, reflecting national loyalties and hopes of higher wages. But there is unease among pro-Ukrainian Crimeans who have complained about the heavy armed presence across the region. “I was born here, my family is here, I have a job here and I am not going anywhere unless there is an all-out military conflict,” said Viktor, a 23-year-old salesman. “It is my home but things will not be the same any more.” Russia’s swift absorption of Crimea has alarmed the Baltic states, which were ruled by the Kremlin for five decades after World War II.

Yanukovich enraged many Ukrainians by turning his back on closer ties with Europe to sign agreements on economic integration with former Soviet overlord Russia.
Germany’s cabinet approved EU plans for closer political cooperation with Ukraine , a government source said, clearing the way for ChancellorAngela Merkel to sign part of a so-called association agreement at an EU summit later this week.
The 28-member bloc is expected to sign a more far-reaching trade accord with Ukraine later.
But maintaining aggressive rhetoric reminiscent of the Cold War, Russia accused Western states of violating a pledge to respect Ukraine’s sovereignty and political independence under a 1994 security assurance agreement, saying they had “indulged a coup d’etat” that ousted Yanukovich.
Moscow, which has said it will retaliate for so far largely symbolic Western sanctions targeting Russian officials, announced on Wednesday it was closing its military facilities to a European security watchdog for the rest of the year.
The Russian Defence Ministry was quoted as saying the signatories of a 2011 Organisation for Security and Cooperation in Europeagreement had exhausted their quotas to inspect Russian military facilities and a planned inspection in the coming days would be the last.
Biden said in Warsaw on Tuesday the United States may run more ground and naval military exercises to help Baltic states near Russia beef up their capacity after what he called Putin’s “land grab” in Ukraine .
The Truxtun, a US guided-missile destroyer started a one-day military exercise with the Bulgarian and Romanian navies in the Black Sea on Wednesday, a US Naval Forces official said.
Washington and Brussels said further sanctions would follow the visa bans and asset freezes imposed so far on a handful of Russian and Crimean officials, drawing derision from Moscow.
On a visit to Japan, which has joined the Western chorus of condemnation of Moscow’s action, close Putin ally Igor Sechin, CEO of Russian oil major Rosneft, said expanding sanctions would only aggravate the crisis.
European Union leaders will consider widening the number of people targeted by personal sanctions when they hold a regular summit in Thursday and Friday, diplomats said, as well as signing the political part of an association agreement with Ukraine’s interim government.
EU officials say they have identified more than 100 potential targets. Some media reports say Sechin and the head of Russian gas monopoly Gazprom are on the wider list.
But some EU officials are wary of moving too fast towards much tougher sanctions, both due to the risk of self-inflicted injury to Europe’s convalescent economy and out of concern not to exhaust the West’s toolbox of non-military measures.
France has said it is considering suspending a contract to supply two helicopter carriers to the Russian military, the first of which is due to be delivered later this year. French officials say they expect Britain, in return, to close its gates and bank vaults to oligarchs close to Putin.
In a rousing patriotic speech to Russian lawmakers denouncing what he called the West’s hypocrisy and double standards, Putin said on Tuesday that Crimea was historically Russian and was returning home.
After signing a treaty to make the Ukrainian region part of the Russian Federation, he told a flag-waving rally in Red Square beneath the Kremlin walls, near where Soviet politburo leaders once took the salute at May Day parades, that Crimea has returned to “home port”.
