AYESHA RASCOE, HOST:
An airstrike this morning in eastern Ukraine killed over 50 people who were hiding in the basement of a school. Several dozen were rescued from the rubble. And in the south, the U.N. is evacuating dozens of Ukrainian civilians, mostly women and children, who were sheltering under a massive steel plant in the port city of Mariupol. NPR's Joanna Kakissis is in Ukraine and joins us now. Good morning, Joanna.
JOANNA KAKISSIS, BYLINE: Good morning, Ayesha.
