During a government meeting Wednesday, the prime minister blasted Russia for its role in inciting unrest in Ukraine, most recently in the eastern region of the country.
"I understand that the Russian Federation has a new product for export. In addition to oil and gas, Russia has started exporting terrorism to Ukraine. And it turns out that only one country in the world -- Russia -- does not see that the Russian subversive groups are committing acts of sabotage on Ukrainian territory."
Yatsenyuk said "Our message to Russia: stop supporting terrorists, condemn them. And we will deal with the situation in our country ourselves."
The prime minister's comments coincided with the Ukrainian government's submission of evidence to the European Union that it says proves Russian special-operations troops have been deployed in Ukraine.
On Sunday, the U.S. Department of State laid out a detailed account that it says proves Russian involvement in the destabilization of eastern Ukraine. The pro-Russian militant takeover of six eastern Ukrainian cities simultaneously on Saturday was "inconsistent with political, grassroots protests" and is instead evidence that Russia "is now using the same tactics that it used in Crimea."
