WASHINGTON — The Obama administration said Monday that any Russian threat to Ukraine's navy would be a "dangerous escalation" of an extremely tense situation .
The State Department said that Washington would hold Moscow directly accountable for such an escalation but did not elaborate on potential consequences. Department spokeswoman Jen Psaki said, however, that she could not confirm if Russia had in fact made such threats.
Earlier Monday, a Ukrainian military spokesman said Russia had issued an ultimatum to the crews of two Ukrainian warships in Crimea, demanding that they immediately surrender or be stormed and seized.
Vladimir Anikin, a Russian defense ministry spokesman in Moscow, dismissed the report of a Russian ultimatum as nonsense, but refused to elaborate.
Secretary of State John Kerry is leaving for Ukraine late Monday and then will travel to France and Italy. He had planned to see his Russian counterpart in Paris, but Psaki said that meeting was no longer certain.
The U.S. and its allies are weighing sanctions on Moscow, in what amounts to a sudden reprise of Cold War sensibilities. Once consideration is whether to bolster defenses in Europe in response to Russia's military advances on Ukraine. Kerry said Sunday that world leaders "are prepared to go to the hilt in order to isolate Russia with respect to this invasion."
Much as when superpower tensions ruled world affairs, missile defense systems and troop levels in Europe have again become urgent questions in Washington and beyond, a renewed reality that may force President Barack Obama's administration to give up its intended foreign policy shift to Asia indefinitely.
Also echoing the era of East-West confrontation, there appears to be little if any taste in the West for a direct military response to Russia's provocation.
Russian President Vladimir Putin gave no indication that he would heed the West's warnings. Hundreds of armed men surrounded a Ukrainian military base in Crimea, a pro-Russian area. In Kiev, Ukraine's capital, Prime Minister Arseniy Yatsenyuk alerted allies that "we are on the brink of disaster."
"This is absolutely the most serious test of our alliances since the Cold War ended," Rep. Marcy Kaptur, D-Ohio, said in a nationally broadcast interview Monday.
"I think it is extremely dangerous. Ukrainians fight and Russians fight," said Kaptur, who has traveled to Ukraine on several occasions and is considered an expert on that part of the world.
Senior Obama administration officials said they believe Russia now has complete operational control over Crimea and has more than 6,000 forces in the region. The U.S. was also watching for ethnic skirmishes in other areas of eastern Ukraine, though the officials said they had not yet seen Russian military moves elsewhere. The officials were not authorized to publicly discuss the situation and spoke on condition of anonymity.
Kerry said he has consulted other world leaders and all are committed to doing what is necessary to isolate Russia diplomatically. President Barack Obama spoke Sunday with German Chancellor Angela Merkel, British Prime Minister David Cameron and Polish President Bronislaw Komorowski.
Kerry planned to travel to Kiev on Tuesday for meetings with the Ukrainian government. Treasury Secretary Jacob Lew said the United States is ready to work with other countries and the International Monetary Fund to provide support for Ukraine's economy.
In Brussels, NATO's secretary-general, Anders Fogh Rasmussen, said Russia's actions have violated a U.N. charter. He said the alliance was re-evaluating its relationship with Russia.
"There are very serious repercussions that can flow out of this," Kerry said.
