Meanwhile, the pro-Russian prime minister of Ukraine's restive Crimea claimed control of all military, police and other security services in the region and appealed to Russia's president for help in keeping peace there. In a statement reported by local and Russian news agencies, Sergei Aksenov declared that the armed forces, the police, the national security service and border guards will answer only to his orders. He said any commanders who don't agree should leave their posts. "Understanding my responsibility for the life and security of citizens, I appeal to the president of Russia Vladimir Putin for assistance in guaranteeing peace and calmness on the territory of the autonomous republic of Crimea," Aksenov said in his statement. Aksenov, the head of the main pro-Russia party on the peninsula, was appointed by the Crimean parliament on Thursday as tensions soared over Crimea's resistance to the new authorities in Kiev, who took power last week. Armed men described as Russian troops on Friday took control of key airports in Crimea, where the Russian Black Sea Fleet is based. Reactions: Russia's upper house of parliament will ask President Vladimir Putin to recall Moscow's ambassador from the United States, the chamber's speaker said on Saturday. Valentina Matviyenko, the head of the Federation Council, asked the Council's Committee on Foreign Affairs to draw up a proposal setting out the demands to Putin. This as Russia's upper house of parliament approved a proposal by President Vladimir Putin to deploy Russian armed forces in Ukraine's Crimea region. The Federation Council voted overwhelmingly to back a proposal to use "the armed forces of the Russian Federation on the territory of Ukraine until the normalization of the socio-political situation in that country." It said the decision took effect immediately. Earlier, Russian President Vladimir Putin has asked the upper house of parliament to approve sending armed forces to Ukraine's Crimea region, the Kremlin said in a statement. "In connection with the extraordinary situation in Ukraine, the threat to the lives of citizens of the Russian Federation, our compatriots, and the personnel of the armed forces of the Russian Federation on Ukrainian territory (in the Autonomous Republic of Crimea) ... I submit a proposal on using the armed forces of the Russian Federation on the territory of Ukraine until the normalization of the socio-political situation in the that country," the statement said. Meanwhile, Russia is refusing to hold talks with Ukraine under the auspices of an agreement that guarantees the country's territorial integrity, Interfax news agency quoted Ukrainian Foreign Minister Andrij Deshchitsya as saying. Ukraine had asked for consultations with Moscow after accusing it of deploying its military in the Crimea region. "We are very worried about today's information that Russia has refused to take part," the minister said. This comes as Russia's Lower House of Parliament, the Duma, has asked President Vladimir Putin to take measures to stabilize the situation in Ukraine's Crimea, the news agency Interfax cited the speaker of the Duma as saying. "The Duma Council adopted an appeal to the president of Russia, in which parliamentarians are calling on the president to take measures to stabilize the situation in Crimea and use all available means to protect the people of Crimea from tyranny and violence," Interfax cited Sergei Naryshkin as saying. This as, the Russian Foreign Ministry said that Moscow is "extremely concerned" about the recent developments in Ukraine's Crimea, which it said confirm the desire of Kiev's politicians to destabilize the situation on the peninsula. "In Russia, we are extremely concerned about the recent developments in Crimea," the foreign ministry said in a statement. "We believe it is extremely irresponsible to further pressure the already tense situation in the Crimea," the foreign ministry said in a statement. On another note, Ukraine is unlikely to receive financial assistance from the International Monetary Fund before April, Ukrainian Finance Minister Oleksander Shlapak was quoted as saying on Saturday. Ukraine, which faces a further $6 billion in foreign debt payments this year, has asked the IMF for financial assistance of at least $15 billion. An IMF team is expected in Kiev next week. International positions: EU foreign ministers will hold an emergency meeting in Brussels on Monday to discuss the situation in Ukraine, an EU diplomat said. "There will be an extraordinary meeting on Ukraine on Monday. Most likely after 1 PM," said the diplomat. This comes as British Foreign Secretary William Hague said he had spoken to Russian Foreign Minister Sergei Lavrov to call for a de-escalation of the situation in Ukraine's Crimea. "Have spoken to Foreign Minister Lavrov to call for de-escalation in Crimea and respect for sovereignty and independence of Ukraine," Hague tweeted. Hague said on Friday he would travel to Ukraine on Sunday to hold talks with the new leadership after Prime Minister David Cameron told Russia to respect the volatile nation's territorial integrity.
