"272 bodies have been found and 251 of them are in refrigerators in Torez train station," Yatsenyuk told reporters at a press conference here.
Ukraine stood ready to transfer the bodies to the Netherlands, Yatsenyuk said, adding that the government in Kiev "has no doubt" that the plane was hit by an anti-aircraft missile.
Yatsenyuk suggested that the Netherlands lead the investigation into the incident.
