KIEV, Ukraine - Russian troops took over Crimea as the parliament in Moscow gave President Vladimir Putin a green light Saturday to use the military to protect Russian interests in Ukraine. The newly installed government in Kiev was powerless to react to the action by Russian troops based in the strategic region and more flown in, aided by pro-Russian Ukrainian groups.
Putin sought and quickly got his parliament's approval to use its military to protect Russia's interests across Ukraine. But while sometimes-violent pro-Russian protests broke out Saturday in a number of Russian-speaking regions of eastern Ukraine, Moscow's immediate focus appeared to be Crimea.
Ignoring President Barack Obama's warning Friday that "there will be costs" if Russia intervenes militarily, Putin sharply raised the stakes in the conflict over Ukraine's future evoking memories of Cold War brinkmanship.
American response: The U.S. is reviewing Russia's military moves in Ukraine and trying to figure out how to respond.
There was a high-level meeting at the White House Saturday after Russia's parliament gave President Vladimir Putin the military go-ahead to protect Russian interests in neighboring Ukraine.
Participants in the meeting included Defense Secretary Chuck Hagel, CIA Director John Brennan, Joint Chiefs of Staff Chairman Gen. Martin Dempsey and Director of National Intelligence James Clapper.
"Russia and the West find themselves on the brink of a confrontation far worse than in 2008 over Georgia," Dmitri Trenin, the director of Carnegie Moscow Center, said in a commentary posted on its website. In Georgia, the Russian troops quickly routed the Georgian military after they tried to regain control over the separatist province of South Ossetia that has close ties with Moscow.
Tensions increased when Ukraine's acting president, Oleksandr Turchynov, made a late night announcement that he had ordered the country's armed forces to be at full readiness because of the threat of "potential aggression."
The latest moves in Ukraine followed days of scripted, bloodless turmoil on the peninsula, the scene of centuries of wars and seen by Moscow as a crown jewel of the Russian and Soviet empires. What began Thursday with the early-morning takeover of the regional parliament building by mysterious troops continued Saturday afternoon as dozens of those soldiers - almost certainly Russian - moved into the streets around the parliamentary complex and seized control of regional airports, amid street protests by pro-Russian Crimeans calling for Moscow's protection from the new government in Kiev.
That government came to power last week in the wake of months of pro-democracy protests against the now-fugitive president, Viktor Yanukovych, and his decision to turn Ukraine toward Russia, its longtime patron, instead of the European Union. Despite the calls for Moscow's help, there has been no sign of ethnic Russians facing attacks in Crimea or elsewhere in Ukraine.
Obama on Friday called on Russia to respect the independence and territory of Ukraine and not try to take advantage of its neighbor's political upheaval.
He said such action by Russia would represent a "profound interference" in matters he said should be decided by the Ukrainian people. He has not said, however, how the U.S. could pressure Moscow to step back from its intervention.
The Russian parliament urged that Moscow recall its ambassador in Washington in response to Obama's speech.
On Friday, Ukraine accused Russia of a "military invasion and occupation" in the Crimea, where Russia's Black Sea fleet is based. Ukrainian Prime Minister Arseny Yatsenyuk called on Moscow "to recall their forces, and to return them to their stations," according to the Interfax news agency. "Russian partners, stop provoking civil and military resistance in Ukraine."
Ukraine's population of 46 million is divided in loyalties between Russia and Europe, with much of western Ukraine advocating closer ties with the European Union while eastern and southern regions look to Russia for support. Crimea, a semi-autonomous region that Russia gave to Ukraine in the 1950s, is mainly Russian-speaking.
In his address to parliament, Putin said the "extraordinary situation in Ukraine" was putting at risk the lives of Russian citizens and military personnel stationed at the Crimean naval base that Moscow has maintained since the Soviet collapse.
Despite Putin's sharp move, there were possible signs Saturday that the Russian leader could soften his approach. Former Ukrainian Prime Minister Yulia Tymoshenko, who was freed a week ago after more than 2 ½ years in prison, was reported to be heading to Moscow for a meeting with Putin on Monday. Putin has had good ties with Tymoshenko in the past, and he may look to her for a possible compromise.
In a statement posted on her party's web site, Tymoshenko urged the U.N. Security Council to meet in Kiev and asked the EU leaders to convene a meeting in Crimea. She urged the West to help protect Ukraine's territorial integrity, asked Ukrainians to remain calm and voiced hope that diplomacy will succeed.
In a note of restraint, Deputy Foreign Minister Grigory Karasin said the motion doesn't mean the president would immediately send additional troops to Ukraine. "There is no talk about it yet," he said.
Putin's spokesman, Dmitry Peskov, also said in televised remarks that while the president "got the entire arsenal of means necessary for settling this situation," he hadn't yet decided whether to use the Russian military in Ukraine or recall the ambassador from Washington as lawmakers suggested.
Putin's motion loosely refers to the "territory of Ukraine" rather than specifically to Crimea, raising the possibility that Moscow could use military force in other Russian-speaking areas in eastern and southern Ukraine, where many detest the new authorities in Kiev.
Pro-Russian protests were reported Saturday in the eastern cities of Kharkiv, Donetsk and Luhansk and the southern port of Odessa. In Kharkiv, 97 people were injured in clashes between pro-Russia demonstrators who flushed supporters of the new Ukrainian government out of the regional government building and hoisted the Russian flag on top of it, according to the Interfax news agency.
Trenin, of Moscow's Carnegie office, said that Putin could be seeking to "include a Crimea within the Russian Federation and eastern and southern regions of Ukraine forming a separate entity integrated with Russia economically and aligned with it politically."
"It is not clear at this point whether Kiev will be left to build a rump Ukraine with the western regions or whether it will be swayed to join the eastern regions," he wrote.
In Crimea, the new pro-Russian prime minister - who came to power after the gunmen swept into parliament on Thursday - claimed control of the military and police and asked Putin for help in keeping peace. There was no visible presence of Ukrainian troops Saturday.
The deputy premier in the Crimean government told Russian news agency RIA Novsti that Ukrainian troops were disarmed and others joined the Crimean people to help patrol the territory. The report couldn't immediately be confirmed.
Crimean Tatars, the historic hosts of the land who make up 12 percent of the island's population and stand strongly for Crimea remaining part of Ukraine, didn't put any visible resistance Saturday.
"The last two or three days have turned around the life of all the people in Crimea," said Refat Chubarov, a Crimean Tatar leader. "They've taken over military bases and civil institutions. That's why Crimean society is filled with fear. People are afraid of everyone and everything."
Crimea only became part of Ukraine in 1954 when Soviet leader Nikita Khrushchev transferred jurisdiction from Russia, a move that was a mere formality when both Ukraine and Russia were part of the Soviet Union. The Soviet breakup in 1991 meant Crimea landed in an independent Ukraine.
Swedish Foreign Minister Carl Bildt summed the situation up simply: "What's happening in Crimea is a Russian takeover. There is no doubt about that," he told Swedish Radio. "Russian military forces are involved and there has been a local takeover of power."
Russia put pressure on Ukraine from another direction when a spokesman for state gas company Gazprom said that Ukraine owed $1.59 billion in overdue bills for imported gas. Sergei Kuprianov said in a statement carried by Russian news wires that the gas arrears would endanger a recent discount granted by Russia.
The Russian payment demand and loss of the discount would accelerate Ukraine's financial crisis. The country is almost broke and seeking emergency credit from the International Monetary Fund.
The tensions barely touched everyday life in Simferopol, the regional capital of Crimea, or anywhere on the peninsula. Children played on swings a few blocks from the parliament building, and most of the city's stores were open. Couples walked hand-in-hand through parks. Crimea's airports - civilian and military - were closed to air traffic, but trains and cars were moving to and from the Ukrainian mainland.
"Things are normal," said Olga Saldovskaia, who was walking through town with her son and grandson. While she doesn't like having gunmen in the streets, like many people in this overwhelmingly ethnic Russian city, she also found their presence reassuring.
"If anyone tries to hurt the people here, they will protect us," said Saldovskaia. She said she sympathized with the pro-democracy protesters in Kiev, but also worries that turmoil in the capital could lead to violence against ethnic Russians. She added, though, that she definitely doesn't want Crimea to become part of Russia.
"Russia is not just all flowers and candy," she said.
Moscow has remained silent on claims that Russian troops are already in control of much of the peninsula, saying any troop movements are within agreed-upon rules governing the semi-autonomous Ukrainian region.
Meanwhile, flights remained halted at Simferopol's airport. Dozens of armed men in military uniforms without markings patrolled the area. They didn't stop or search people leaving or entering the airport, and refused to talk to journalists.
AP journalists crossing into Crimea from mainland Ukraine were briefly stopped at a checkpoint manned by troops in unmarked camouflage uniforms as well officers in uniforms of the Berkut, the feared riot police that cracked down on anti-Yanukovych protesters before he fled the capital a week ago.
