A Russian airstrike devastated a maternity hospital Wednesday in the besieged port city of Mariupol amid growing warnings from the West that Moscow’s invasion is about to take a more brutal and indiscriminate turn. Ukrainian officials said the attack wounded at least 17 people.The ground shook more than a mile away when the Mariupol complex was hit by a series of blasts that blew out windows and ripped away much of the front of one building. Police and soldiers rushed to the scene to evacuate victims, carrying out a heavily pregnant and bleeding woman on a stretcher as light snow drifted down on burning and mangled cars and trees shattered by the blast.Another woman wailed as she clutched her child. In the courtyard, a blast crater extended at least two stories deep.
