If you're looking for some weekend listening, you could do a lot worse than listen to our very own Brian Whitmore's Power Vertical podcast. It's on Crimea.
Interfax was reporting earlier that OSCE monitors were refused entry -- once again -- to Crimea. More from the wires:
The Organization for Security and Co-operation In Europe (OSCE) says its military observers have again been denied access to Crimea and are heading back to the Ukrainian city of Kherson to plan their next step.
The OSCE's announcement via Twitter on Friday came after news agencies reported that armed men at a checkpoint blocked two buses carrying OSCE observers from entering Crimea.
The Russian Foreign Ministry said Friday that the OSCE observers had failed to obtain "official invitations" from the Crimean authorities.
The OSCE team of 47 military and civilian observers was similarly blocked on Thursday and spent the night in Kherson, the nearest big town north of the peninsula.
And more on the recent IMF visit to Kyiv. The Ukrainian coffers are pretty much empty and the country desperately needs financial assistance:
The head of a delegation from the International Monetary Fund that just completed a visit to Kyiv said he was "impressed with the authorities' determination."
Reza Moghadam said Friday he had "productive" talks with Prime Minister Arseniy Yatsenyuk and his economic team during the mission's March 6-7 visit.
Moghadam said the IMF is prepared to help "the people of Ukraine and support the authorities' economic program to put Ukraine firmly on the path of good economic governance and sustainable growth while protecting the poor and vulnerable."
The IMF team also met with acting President and speaker of parliament Oleksander Turchynov, Governor of the National Bank Stepan Kubiv, and the finance and economic development and trade ministers.
The new Ukrainian government has said it inherited virtually empty coffers after the previous government was ousted.

Interpretermag.com has a report about hacker attacks against Ukrainian media and the interim government.
"'The nature of the attacks is such that the control centers are scattered around, and an attack could be launched from anywhere – from Russia, Ukraine, America or China,' Yevgeny Bespalov, General Director of the Friendly Runet told Gazeta.ru. 'They are difficult to identify.'"

More from the wires of the "USS Truxton" making its way to the Black Sea.
A U.S. warship has passed through Turkey's Bosphorus straits on its way to the Black Sea.
Turkish television on Friday showed the USS Truxton, a navy guided-missile destroyer, heading north for what the U.S. military has described as a "routine" deployment scheduled well before the crisis in Ukraine.
The ship is due to conduct training exercises with naval forces from NATO allies Bulgaria and Romania.
Earlier this week, Washington announced plans to put more U.S. fighter jets on a NATO air patrol mission in the Baltics to reassure allies alarmed by Russia's effective seizure of Ukraine's Crimea peninsula.

From the wires. The head of Russia's state-owned gas giant Gazprom has said his company cannot supply Ukraine with gas for free and warned about a cut-off.
Aleksei Miller said Ukraine's unpaid bill for gas supplies had reached some $1.89 billion. Miller said, "This means that in fact, Ukraine has stopped paying for gas."
Miller said Gazprom might suspend supplies to Ukraine, which would also mean suspending supplies of Russian gas that transit Ukraine on route to countries further west in Europe.
Miller mentioned it could mean a return to the situation in early 2009 when disagreements between Moscow and Kyiv led to a suspension of gas supplies to Europe via Ukraine.
"Under an agreement with Ukraine, Russia cannot base more than 25,000 men in Sevastopol and must negotiate with the Ukrainians if it wants to add new ships. The advent of a Kremlin-controlled Crimea would allow Russia to expand and modernize the fleet as it wished."
