A Russian airstrike on a Mariupol maternity hospital that killed three people is stirring outrage, with Ukrainian and Western officials branding it a war crime. As talks to reach a broad cease-fire failed Thursday, emergency workers renewed efforts to get vital food and medical supplies into besieged cities and get traumatized residents out. Ukrainian authorities say a child was among the dead in Wednesday’s attack in the crucial southern port. Images of pregnant women covered in dust and blood dominated news reports in many countries. The 2-week-old war sparked by Russia’s invasion has killed thousands of soldiers and civilians, driven more than 2 million people from Ukraine and shaken the foundations of European security.
