14:15 OSCE Representative on Freedom of the Media Dunja Mijatović has warned that the current situation in Ukraine has led to a media freedom crisis.

I call on all those responsible to stop the information war, ensure journalists' safety in Crimea and elsewhere and immediately start to de-escalate the situation by allowing media to report freely," Mijatović said.
"In times of crisis, members of the media are among the first to be attacked to deprive citizens from receiving information from a variety of sources. The recent demonstrations in Kyiv and other cities and what we are seeing across Crimea are clear examples of this."

9:39 Here is a statement released by the Kremlin on the phone call between Putin and Obama:
The presidents continued their discussion of the critical situation unfolding in Ukraine. During the conversation, they addressed the differences in approaches and assessments of the causes for the current crisis and the present state of affairs.
In particular, Vladimir Putin noted that the current Ukrainian government, which came to power as the result of an unconstitutional coup and was not supported by a nationwide mandate, is imposing entirely illegitimate decisions onto Crimea and the eastern and southeastern regions of Ukraine. Russia cannot ignore calls for help on this matter and is responding accordingly, in full compliance with international law.
The President of Russia stressed the paramount importance of Russian-US relations for ensuring stability and security in the world. These relations should not be sacrificed due to disagreements on individual international issues, even if they are very significant.
The leaders of the two nations agreed that Foreign Minister Sergei Lavrov and Secretary of State John Kerry will continue close communication.
9:31The chair of Russia's upper house of parliament Valentina Matviyenko said she is sure there will be no war between Russia and Ukraine.
"We are absolutely sure there will never be war between two brotherly nations," she said.
9:22 The Russian foreign ministry tweeted:
8:44 Interpol says it is considering a request by Ukraine's new authorities for issuing a Red Notice or international wanted persons alert against ousted president Viktor Yanukovich. Charges against the fugitive president include abuse of power and murder.
A Red Notice is "one of the ways in which Interpol informs its member countries that an arrest warrant has been issued for an individual by a judicial authority," Interpol said.
"A Red Notice seeks the location and arrest of wanted persons with a view to extradition or similar lawful action. It is not an international arrest warrant."
Yanukovich was last seen in Russia, which is a member state of Interpol.
Interpol said: "A request by Ukrainian authorities for an Interpol Red Notice, or international wanted persons alert, for the arrest of Victor Yanukovych on charges including abuse of power and murder has been received by Interpol General Secretariat headquarters in Lyon, France.
"The request, received on Wednesday 5 March 2014, is being assessed by Interpol's Office of Legal Affairs to determine whether it conforms with the Organization's constitution and rules.
"All Interpol member countries have been informed of the ongoing review and all references to the Ukrainian."
8:35 US President Barack Obama pushed for a diplomatic solution to the Ukraine crisis in his telephonic conversation with Vladimir Putin.
Here is a White House statement on the call:
President Obama spoke for an hour this afternoon with President Putin of Russia. President Obama emphasized that Russia's actions are in violation of Ukraine's sovereignty and territorial integrity, which has led us to take several steps in response, in coordination with our European partners. President Obama indicated that there is a way to resolve the situation diplomatically, which addresses the interests of Russia, the people of Ukraine, and the international community. As a part of that resolution, the governments of Ukraine and Russia would hold direct talks, facilitated by the international community; international monitors could ensure that the rights of all Ukrainians are protected, including ethnic Russians; Russian forces would return to their bases; and the international community would work together to support the Ukrainian people as they prepare for elections in May. President Obama indicated that Secretary Kerry would continue discussions with Foreign Minister Lavrov, the government of Ukraine, and other international partners in the days to come to advance those objectives.
