that is a direct quote from the mayor of mariupol who estimates 20,000 there are dead. enough to fill every seat at madison square garden. an estimated 100,000 people remain in the port sieged city. cnn matt rivers was at a train station in lviv in western ukraine today and he spoke to some who had just escaped the horrors of the south. reporter: the train was designated just for evacuees. if all went to plan it would arrive in lviv packed with hundreds fleeing war. instead, just a handful of families finally found safety, including polina and her daughter who fled marm. they are furious there are not more who got out. she says so many should have been evacuated but the russians kept shelling. they are not human beings. i don t know who gave birth to them. horrific.
