Putin reveals his ordering Russia’s annexation of Crimea

President Vladimir Putin has revealed the moment he says he gave the secret order for Russia's annexation of Crimea and described how Russian troops were ready to fight to rescue Ukraine's deposed, pro-Moscow president.

In a trailer shown on Sunday for an upcoming documentary on state-run Rossiya-1 television called , Putin openly discusses Moscow's controversial grabbing of Crimea a year ago.

Putin recounts an all-night meeting with security services chiefs to discuss how to extricate deposed president Viktor Yanukovych, who had fled a pro-Western street revolt in the Ukrainian capital, Kiev.

"We ended at about seven in the morning," Putin says. "When we were parting, I said to my colleagues: we must start working on returning Crimea to Russia."

Four days after that February meeting last year, unidentified soldiers took over the local parliament in Crimea and deputies hurriedly voted in a new government. The Ukrainian province was then formally annexed by Moscow on March 18, triggering international condemnation.

The military operation was initially kept secret and despite the increasingly obvious actions of unmarked Russian forces on the ground, Moscow insisted that only locals were involved in the upheaval. Later, the Kremlin conceded that it had been behind the power grab.
