100% False....according to the international observers and Western governments, the 2010 presidential election in Ukraine was conducted fairly and the outcome reflected the will of the people involved.
EU endorses Ukraine election result
World Digest: International observers say Ukrainian election was free and fair
Fast forward to 2013...Yanukovich and his Regions party are ready to sign a economic/trade agreement with the Europeans but the EU insisted that the charges against former PM Yulia Tymoshenko be dropped as part of the package...a prime example of Western meddling in the domestic political affairs of Ukraine and something which threatened the elected majority of the Ukrainian parliament.
Along come the Russians with an even better economic package (30% gas subsidies, debt forgiveness, a much larger government loan deal), and the faltering EU plan is cast aside. Yanukovich and his party decide to take the Russian deal, and for a brief period of time at the end of 2013 the international credit agencies even raise Ukraine's sovereign debt rating on the strength of the Russian deal.
Having determined that the upcoming 2014 presidential election was not going to be winnable because the opposition to Yanukovich was divided into three warring camps and the one person who might have united them (Tymoshenko) was serving a prison sentence for corruption, the West decides to overthrow the democratically elected Ukrainian president and install their own puppet government instead.
Extremists from Prevy Sektor are given the green light to foment violence in the streets of Kiev, and the Maidan protest designed to pressure the Yanukovich government to align themselves with the West becomes the Maidan Massacre designed to overthrow the elected government.
Pure Russian propaganda.
The violence was caused by Russian FSB and Spetsnaz who were working with the Ukrainian secret police “Berkut” to try and prop up Yanukovych.
Once Yanukovych fled, those Russian assets moved to the Donbas where they started whipping up anti-ukrainian sentiment.
