Crimean appeals to Putin

The new pro-Moscow leader of Ukraine's autonomous Crimea region has asked Russian President Vladimir Putin for help to ensure peace. A Kremlin source said it would "not leave unnoticed" the request from Sergiy Aksyonov. US President Barack Obama warned Moscow against intervention after mysterious troop movements. Ukraine's interim Prime Minister, Arseniy Yatsenyuk, accused Russia of seeking to provoke an escalation. He was speaking at the first meeting of his cabinet, installed after the overthrow of President Viktor Yanukovych. The spectre of armed conflict in Crimea will be at the top of a long agenda, the BBC's Mark Lowen reports from the region, according to BBC.
