Putin says Ukraine's future in doubt as ceasefire collapses: 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 port city of Mariupol collapsed amid scenes of terror in the besieged town. 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. He also hit out at Western sanctions that have crippled Russia's economy and sent the value of its currency tumbling. Ten days after Russian forces invaded, the struggle to enforce the temporary cease-fires in Mariupol and the eastern city of Volnovakha showed the fragility of efforts to stop the fighting across Ukraine. Ukrainian officials said Russian artillery fire and airstrikes had prevented residents from leaving before the agreed-to evacuations got underway. Putin accused Ukraine of sabotaging the effort. A third round of talks between Russia and Ukraine will take place Monday, according to Davyd Arakhamia, a member of the Ukrainian delegation. He gave no additional details, including where they would take place. Kyiv’s central train station remained crowded with people desperate to flee. “People just want to live,” one woman, Ksenia, said. Elsewhere in the capital, in a sign of nerves near breaking point, two people on a sidewalk froze in their tracks at the sound of a sharp bang. It was a garbage truck upending a bin.
