Russians push deeper into Mariupol as locals plead for help

Russian forces have pushed deeper into Ukraine’s besieged and battered port city of Mariupol

LVIV, Ukraine -- Russian forces pushed deeper into Ukraine's besieged and battered port city of Mariupol on Saturday, where heavy fighting shut down a major steel plant and local authorities pleaded for more Western help.

The fall of Mariupol, the scene of some of the war's worst suffering, would mark a major battlefield advance for the Russians, who are largely bogged down outside major cities more than three weeks into the biggest land invasion in Europe since World War II.

“Children, elderly people are dying. The city is destroyed and it is wiped off the face of the earth,” Mariupol police officer Michail Vershnin said from a rubble-strewn street in a video addressed to Western leaders that was authenticated by The Associated Press.

Details also began to emerge Saturday about a rocket attack that killed as many as 40 marines in the southern city of Mykolaiv on Friday, according to a Ukrainian military official who spoke to The New York Times.
