SIMFEROPOL, Ukraine — Lawmakers in Crimea voted unanimously Thursday to split from Ukraine and join Russia instead, and scheduled a referendum in 10 days for voters on the disputed peninsula to support or reject their decision.
Russian lawmakers, clearly savoring the action, said that if Crimea votes to become part of Russia, they will plan legislation that would speed up the procedure of making that happen.
The Obama administration slapped new visa restrictions against Russian officials and entities and some Ukrainians in Crimea who oppose the new Ukraine government in Kiev, and cleared the way for upcoming financial sanctions, as the West began punishing Moscow for refusing to withdraw its troops from the strategic region that also houses Russia's Black Sea fleet.
Ukraine's prime minister said the Crimean lawmakers' decision is illegitimate, and a European Union official warned that results of any referendum will not be recognized by the West.
The 100-seat parliament in Crimea, which enjoys a degree of autonomy under current Ukrainian law, voted 78-0, with eight abstentions in favor joining Russia and for holding the referendum on March 16. Local voters also will be given the choice of deciding to remain part of Ukraine, but with enhanced local powers.
"This is our response to the disorder and lawlessness in Kiev," said Sergei Shuvainikov, a member of the local Crimean legislature. "We will decide our future ourselves."
In Moscow, a prominent member of Russia's parliament, Sergei Mironov, said he has proposed a bill that would simplify the procedure for Crimea to join Russia. However, another senior lawmaker, Leonid Slutsky, said Russia's parliament could only consider such a motion after Crimea's referendum.
A senior Western diplomat said that the EU leaders, meeting in Brussels to discuss their response to Moscow's move, "will send a clear message that the referendum won't be recognized." The diplomat spoke on condition of anonymity because he wasn't allowed to discuss the leaders' closed-door talks publicly.
On Tuesday, President Vladimir Putin said Russia had no intention of annexing Crimea, while insisting its population has the right to determine the region's status in a referendum. Putin called a meeting of his Security Council on Thursday to discuss Ukraine.
A referendum had previously been scheduled in Crimea on March 30, but the question to be put to voters was on whether their region should enjoy "state autonomy" within Ukraine.
Crimea's new leader has said pro-Russian forces numbering more than 11,000 now control all access to the peninsula in the Black Sea and have blockaded all military bases that have not yet surrendered.
The West has joined the new Ukrainian leadership in Kiev in demanding that Russia pull its forces back from Crimea.
The U.S. sanctions announced Thursday targeted an unspecified and unidentified number of people and entities that the Obama administration accuses of threatening Ukraine's sovereignty and territorial borders. They were announced in Washington as U.S. Secretary of State John Kerry headed into a meeting with Russian Foreign Minister Sergey Lavrov in Rome on the sidelines of a diplomatic forum about Libya.
In Brussels, European Union leaders were gathering to decide what sort of sanctions they can impose on Russia unless it withdraws its troops from Ukraine or engages in credible talks to defuse the situation.
"We need to send a very clear message to the Russian government that what has happened is unacceptable and should have consequences," British Prime Minister David Cameron said as he arrived at an emergency meeting of the bloc's 28 leaders.
But the European leaders appeared divided between nations close to Russia's borders and some Western economic powerhouses — notably Germany — that were taking a more dovish line.
Moscow has threatened to retaliate if any punitive measures are put in place.
German Vice Chancellor and Economy Minister Sigmar Gabriel met with Putin for about an hour in Moscow on Thursday, and said the Russian leader "said neither yes nor no" to establishing a contact group, a small number of diplomats from major powers to spearhead negotiations. Gabriel said Putin only agreed to talk more about the proposal in the coming days.
Ukrainian Prime Minister Arseniy Yatsenyuk was in Brussels to meet with the EU leaders, and clearly agitated over the latest developments in Crimea, urged the Europeans to take strong action against Russia and its Crimean allies.
"This so-called referendum has no legal grounds at all," he told a news conference. "Crimea was, is, and will be an integral part of Ukraine."
In Simferopol, Crimea's capital, about 50 people rallied outside the local parliament Thursday morning waving Russian and Crimean flags. Among the posters they held was one that said "Russia, defend us from genocide."
"We are tired of revolutions, maidans and conflicts, and we want to live peacefully in Russia," said one of the bystanders, Igor Urbansky, 35. "Only Russia can give us a peaceful life."
Maidan is the name of the downtown square in Kiev where tens of thousands of protesters contested the rule of Ukrainian President Viktor Yanukovych, who fled to Russia.
Not all in this city favored the lawmakers' vote to secede from Ukraine.
"This is crazy. Crimea has become Putin's puppet," said Viktor Gordiyenko, 46. "A referendum at gunpoint of Russia weapons is just a decoration for Putin's show. A decision on occupation has already been made."
Svetlana Savchenko, another Crimean lawmaker, said the choice she and her fellow deputies took in favor of joining Russia will force Moscow to make a decision.
"This is our principled position," she told The Associated Press. "Now the Russian Federation must begin a procedure — will it take us in or not?"
Rustam Temirgaliev, first vice premier of the Crimean government, said preparations are underway already to bring Crimea into Russia's "ruble zone."
"At the present moment a large, important group of specialists from Russia is at work, preparing to assure the entry of Crimea into the Russian Federation," Temirgaliev said.
At a news conference in Kiev, representatives of the Organization for Security and Cooperation in Europe returning from Crimea expressed concern the referendum might stir up new clashes and provocations.
"The situation might seem quiet, almost normal if you go to the streets," Tim Guldimann, said the personal envoy of the Swiss OSCE chair. "However, it's extremely tense and I would consider this as a miracle that bloodshed could be avoided so far given the political and even military circumstances on the ground."
On Wednesday, a U.N. envoy left Crimea after being told to get out by armed men. On Thursday, an OSCE military observer mission of 37 people from 18 countries, including the United States, was stopped at the Crimean border, organization spokesperson Tatyana Baeva said in Vienna. She said it wasn't clear who had stopped the mission, which had been formed at Ukraine's request to help monitor the tense situation in Crimea.
Under the Soviet Union, Crimea belonged to the Russian Federation until it was transferred to Ukraine in 1954 by Soviet leader Nikita Khrushchev. Ukraine became independent after the 1991 Soviet collapse.
Concern that the turmoil could engulf eastern Ukraine grew after hundreds of demonstrators — many chanting "Russia! Russia!" — stormed a government building on Wednesday in Donetsk, a major industrial center near the Russian border.
Clashes between protesters and police broke out early Thursday in Donetsk as police cleared demonstrators from the regional administration center. The Ukrainian flag once again was hoisted over the building, and about 100 Ukrainian Interior troops could be seen in and around it. Two large trucks were parked in front to block the approach.
The European Union on Wednesday extended $15 billion in aid to help support the new Ukrainian government, which took over in late February after months of protests drove out Yanukovych, the Moscow-supported president.
The EU also imposed asset freezes against 18 people held responsible for embezzling state funds in Ukraine, including Yanukovych, his son and some of his closest allies.
