TODAY: Kiev, Nato and U.S. say Russia preparing to invade Ukraine; Kiev returns to E.U. deal; OSCE to send monitors to Ukraine; Belarus says annexation of Crimea a bad precedent; sanctions hit Russian economy, Kremlin retaliates; two killed at new Sochi resort.

Russia says it is in compliance with international troop limits on the border with Ukraine, but Nato’s top military commander claimed that Russia is massing troops on the Ukrainian border and that they are ‘very, very sizeable and very, very ready’; he suggested that Moldova’s Trans-Dniester region could be the next target.  Of the 18,000 troops initially stationed in Crimea, only 2,000 have left.  The White House yesterday warned of a full invasion of Ukraine, and said that troop buildup near the border ‘creates the potential for incidents’.  Ukraine’s foreign minister also says he sees the risk of war growing, and that Ukrainians are preparing to ‘defend their homeland’.  Local defence groups have formed in Ukraine’s Donetsk region to protect themselves as increasing tensions are felt.  A truce made between Ukrainian and Russian defense ministries last week has expired, leading to further Russian takeovers of Crimea’s remaining military bases, including the base in Feodosia this morning.  Ukraine, meanwhile, has taken up the remains of the abandoned E.U. deal that started the whole crisis.  World leaders are gathering in The Hague to discuss the situation.  President Vladimir Putin and German Chancellor Angela Merkel apparently agreed that the Organisation for Security and Cooperation in Europe will send monitors to Ukraine.  Belarussian President Alexander Lukashenko accepts Russia’s annexation of Crimea, but said that it set a ‘bad precedent’.
