The mayor of Ukraine's southern port city Odesa has slammed Russia President Vladimir Putin in an interview with Euronews.
Gennadiy Trukhanov was speaking after a Russian strike destroyed a warehouse that he said had no connection to Ukraine's military.
Putin said initially he was invading Ukraine to "denazify" and demilitarise the country.
But Trukhanov and Kyiv claim Russia has been behind the indiscriminate shelling of civilian areas.
Trukhanov told Euronews Odesa could become the "next Mariupol".
"I would like to say to Putin: 'Listen, nobody believes in it anymore. Nobody believes you. Stop it, pull off your mask'," he told Euronews' international correspondent Anelise Borges.
"Today you represent a different country: you are a country of aggression. Today, without any reason, you invaded a sovereign state. You are killing people here, even children.
"You are destroying everything we built here. Savagely you are destroying everything in Ukraine. Stop the war in Ukraine. Withdraw your troops."
