President Putin, who secured permission from his parliament Saturday to use military force, told U.S. President Barack Obama he had the right to defend Russian interests and nationals. Ukraine's actual government has mobilized troops and called up military reservists. The Ukrainian government suspects Russia to use a previously verified formula by trying to escalate tension in the region to force the apparition of a separatist request.
It seems that an ultimatum told Ukraine’s military to surrender by 4am CET or face assault, according to the news agencies based on military sources. If so, the tension will escalate quickly in a short time. The international reaction is very strong. The US President, Barack Obama, affirmed that now Russia is “on the wrong side of history”, violating international law. “EU has agreed that Russia's actions are an aggression” according to Swedish Foreign Minister Carl Bildt, after leaving an emergency European Union session in Brussels. The UK Prime Minister David Cameron announced immediate sanctions against Russia. US Vice President Joe Biden warned Russian Prime Minister Dmitry Medvedev during a phone call of "increasing political and economic isolation" if Russia does not pull back its forces from Ukraine.
Russia's G8 partners have condemned Moscow's military buildup in Crimea and even suspended preparations for the G8 summit in Sochi, Russia, in June. "It is now of the utmost importance to install calm and de-escalate tensions immediately through dialogue," U.N. Secretary-General Ban Ki-moon told to the media. NATO will hold fresh emergency talks on the Ukraine crisis Tuesday, after Poland requested consultations with its allies.
Economic support to Ukraine was promised by many countries and a mission of FMI is also scheduled to arrive in Ukraine.
