Russian President Vladimir Putin has fallen under the spell of Satan and faces eternal damnation unless he repents, a top Ukrainian clergyman said Saturday in an unusually blunt statement that squarely blamed the Russian leader for the war in Ukraine.

Patriarch Filaret heads the Kiev Patriarchate, a branch of the Orthodox Church that broke away from Moscow in 1992 after the fall of the Soviet Union and the declaration of an independent Ukraine.

His church, a rival of the Moscow Patriarchate, which is closely linked to Putin, strongly supports Ukrainian nationhood and the Kiev government's struggle to defeat pro-Russian separatists in eastern Ukraine.
