Moscow, December 13 (Interfax) - Russian Prime Minister Dmitry Medvedev believes Ukraine will have to overcome a tectonic fault that threatens the state's existence as such.

"It seems to me that Ukrainian society will have to overcome a tectonic fault that has formed in it. This fault threatens the state's stability and actually its existence. Surely, we are greatly alarmed when following the emotions that civil society in Ukraine is demonstrating," Medvedev said at a press conference in Moscow on Friday.
