Secretary of State John Kerry said Thursday there is no doubt that Russia has sent armed men who have occupied government buildings in several eastern Ukrainian towns."The world knows that peaceful protesters don't come armed with grenade launchers and automatic weapons,the latest issue from the Russian arsenal,hiding the insignias on their brand new matching military uniforms and speaking in dialects that every local knows come from thousands of miles away.The world knows that the Russian intelligence operatives arrested in Ukraine didn't just take a wrong turn on the highway.In fact, we have seen soldiers wearing uniforms identical to the ones Russian soldiers wore in Crimea last month," said Kerry.Kerry said Ukraine promptly began implementing steps it agreed to in Geneva earlier this month."From day one, Prime Minister Arseniy Yatsenyuk has kept his word. He immediately agreed to help vacate buildings.He suspended Ukraine's counterterrorism initiative over Easter,choosing de-escalation despite Ukraine's legitimate, fundamental right to defend its own territory and its own people," said Kerry.Kerry also said Russia has acted to further destabilize Ukraine to pave the way for more incursions in the country's east.
