Putin says Ukraine's future in jeopardy as ceasefire for city collapses

Russian president says Western sanctions akin to declaration of war and attempt to impose a no-fly zone in Ukraine would lead to catastrophic consequences.

Russian President Vladimir Putin warned Saturday that Ukrainian statehood is in jeopardy and likened the West's sanctions on Russia to “declaring war,” while a promised cease-fire in the besieged port city of Mariupol collapsed amid scenes of terror.

With the Kremlin’s rhetoric growing fiercer and a reprieve from fighting dissolving, Russian troops continued to shell encircled cities and the number of Ukrainians forced from their country grew to 1.4 million. By Saturday night Russian forces had intensified their shelling of Mariupol, while dropping powerful bombs on residential areas of Chernihiv, a city north of Kyiv, Ukrainian officials said.
