*  – US Secretary of State John Kerry said on 7 April 2014 that the events "did not appear to be spontaneous" and called on Russia to "publicly disavow the activities of separatists, saboteurs and provocateurs" in a phone call to his Russian counterpart Sergei Lavrov. A spokeswoman for the White House National Security Council claimed that the separatists appeared to be supported by Russia. "We saw similar so-called protest activities in Crimea before Russia's purported annexation," she said in a statement, adding: "We call on President (Vladimir) Putin and his government to cease all efforts to destabilise Ukraine, and we caution against further military intervention." US-Ukraine ambassador Geoffrey R. Pyatt characterised the pro-Russian militants as terrorists.
