Putin says will not abandon Russians in Ukraine to nationalists - RIA
More than 9,000 people have been killed in fighting in eastern Ukraine between Russian-backed separatists and Ukrainian troops since April 2014. Moscow says Ukrainian nationalists pose a threat to ethnic Russians and Russian-speaking Ukrainians in the region.
According to RIA, Putin also said Russia would continue to improve its nuclear arsenal, but added that it would not wield the "nuclear big stick".
