Russian President Vladimir Putin says Moscow must do all it can to prevent extremism and stop "color revolutions" from reaching Russia.

He told his advisory Security Council on November 20 in Moscow that "we see what tragic consequences the wave of so-called color revolutions led to," referring to popular uprisings in former Soviet republics.

Moscow has charged the West with meddling in Ukraine, a charge that the EU and United States deny.

Separately, Ukrainian Prime Minister Arseniy Yatsenyuk said in Kyiv on November 20 that the EU and the United States should join Ukraine in forcing Russia to stick to a peace deal to end the separatist conflict there.

"Putin's actions are a threat to everyone, the global order, global peace," Yatsenyuk told a news conference.
