At least 10 people—including three children—were killed in a devastating Russian missile attack on the city of Kramatorsk in eastern Ukraine on Tuesday, officials said. Two of the children were twin sisters, both 14, according to local reports. The Department of Education of the Kramatorsk City Council named the girls as Yuliya and Anna and said they would have turned 15 in September before a “Russian rocket stopped the beating of the hearts of two angels.” Explosions tore through a crowded pizza restaurant and a shopping area leaving another 56 people injured, according to Ukrainian emergency services. One witness told the BBC that he’d seen “dead people, people screaming, people crying, huge chaos.” A Belgian journalist also said he’d left the popular Ria Lounge restaurant mere minutes before the strike. “Now I can hear people screaming underneath the rubble as rescuers are trying to save them,” Arnaud De Decker said. Ukrainian authorities on Wednesday announced that a local man was suspected of directing the strike, allegedly filming the restaurant in secret and informing Russians about the location’s popularity.
