"I believe that if Petr Alekseyevich [Petro Oleksiyovych Poroshenko] truly is a President of Peace, the way he refers to himself, and if he was truly sincere while participating in the talks on the Minsk agreement, then he needs to stand up for his rightfulness and thus neutralize those who want to plunge Ukraine into a civil war once again, " Lavrov said.
According to the Russian Foreign Minister, Poroshenko is currently trying to "outdo the radicals on their own territory," as showcased by the recent appointment of the ultra-nationalist Right Sector leader, Dmytro Yarosh, as an adviser to Ukraine's General Staff chief Viktor Muzhenko.
Members of the Right Sector movement took an active part in clashes with police and takeovers of administrative buildings in Ukraine in January 2014, prior to the February 22 government coup.
On November 2014, Russian Supreme Court declared the Right Sector an extremist group and banned its activities on the Russian territory.
Crimea seceded from Ukraine last March following the referendum on which 96 percent of its population, mostly Russian speakers, backed reunification with Russia. Kiev still considers Crimea a part of Ukraine.
