The Pentagon said on Thursday that Russia's persistent troubles in Ukraine likely led to latest shake-up in military leadership, and urged Moscow to end the war instead turning to new generals to oversee the nearly year-long invasion.
Russia on Wednesday appointed Chief of the General Staff Valery Gerasimov to oversee the military campaign in Ukraine. Only last October, Russia had put Sergey Surovikin in that position. Surovikin will now stay on as a deputy of Gerasimov.
