KIEV, Ukraine -- Even before residents of Crimea went to the polls Sunday, Ukrainians and Russians knew the result of the vote would be to secede from Ukraine and join Russia. So, when results showed that more than 95 percent of the voters favored joining Russia, it didn't really turn any heads.

What did, however, was news footage showing ranks of Russian tanks lining the road near Kerch in eastern Crimea, apparently preparing to move, while other footage showed Ukrainian tanks moving to defend the border with Russia in the Donetsk district, on the eastern edge of the country.

The prospect of a strengthened Russian force moving north from Crimea into other parts of Ukraine, or Ukrainian tanks engaging potential Russian invaders in the east, raised tensions after weeks when the Russian takeover of Crimea was largely without bloodshed.

The interim Ukrainian government pledged to spend an additional $7 billion on its underfunded military.

On Monday, Crimea's rump government is expected to ask that Russia annex the territory. The Russian Defense Ministry said that Ukrainian soldiers still in Crimea had until Friday to leave the territory or face military action by Russian forces.

Crimean officials said 80 percent of eligible voters turned out for the referendum, which offered only two options: secede from Ukraine and join Russia or revert to the 1992 constitution that gave Crimea vast autonomy. There was no option to maintain the status quo.

With 50 percent of the ballots counted, union with Russia was favored by 95.5 percent, with 3.5 percent choosing more autonomy.


One percent of the ballots were ruled invalid.

In a phone call with Russian President Vladimir Putin, President Barack Obama reiterated that the referendum result "would never be recognized by the United States and the international community," according to a White House statement.

But the statement didn't indicate any change of heart from Putin despite Obama's renewed warning that the U.S. is "prepared to impose additional costs on Russia for its actions."


The White House issued a straightforward statement: "We reject the 'referendum' that took place today in the Crimean region of Ukraine. No decisions should be made about the future of Ukraine without the Ukrainian government. Moreover, this vote was not necessary. The Ukrainian government has made clear its willingness to discuss increased autonomy for Crimea."

The European Union and European Council heads issued a joint statement, noting there would be consequences, and those would be discussed Monday in Brussels.

"The referendum is illegal and illegitimate and its outcome will not be recognized," the statement said. "We reiterate the strong condemnation of the unprovoked violation of Ukraine's sovereignty and territorial integrity and call on Russia to withdraw its armed forces."

Russian and Crimean officials gave every indication that they intend to proceed quickly with formalizing the Russian annexation. Crimean Prime Minister Serhiy Aksyonov called the decision historic and said he would seek Russian agreement on Monday, with the Russian Parliament expected to take up the matter Wednesday. Crimean Deputy Prime Minister Rustam Ilmirovich Temirgaliev said the region would replace the Ukrainian currency, the hryvnia, with Russian rubles in April.

The Friday deadline for Ukrainian troops to leave Crimea came in an announcement from the Russian Ministry of Defense, which said it had agreed to "a truce" to allow the Ukrainian forces a work week to get back to the Ukrainian mainland.

Russian troops without insignia have been occupying Crimea for two weeks and have surrounded several military bases still occupied by Ukrainians. Ukrainian soldiers said last week that their Russian counterparts had told them that after the referendum, their presence would be considered illegal and that they would be given the choices of disarming and returning to Ukraine, taking Russian citizenship or preparing to defend themselves.

Ukrainian Defense Minister Ihor Tenyukh, in an interview with Ukrainian Interfax news service, said Ukrainian troops would not leave Crimea.

He said Ukrainian combat readiness remains at its highest level, and that in past few days 40,000 Ukrainians have signed up for National Guard duty.

While Russian troops have controlled Crimea since the end of February, experts and military officials note that once Crimea is broken away from Ukraine, it will lose access to water and fuel, which flow to it from the Ukrainian mainland.

Crimea's isolation has led military experts to conclude that Russia may move to annex other Ukrainian regions needed to provide a land corridor connecting Crimea to Russia.

Stephen Long, an international security expert at the University of Richmond, said that he doubts international outcry over an expanded Russian land grab would deter Putin.

"Putin is willing to endure any level of international condemnation in the pursuit of his interests in the Russian near abroad," Long said. "What is stunning about this story is that he appears to believe that he can change the narrative through sheer force of will."

"What is not clear," Long added, "is whether Mr. Putin believes that he is actually changing public perception, or whether he simply cares so little about it that he sees no reason to offer a more convincing argument for his actions."
