By Tom Balmforth LONDON, July 30 (Reuters) - Russia likely used a North Korean missile for a deadly strike that killed a family near the Ukrainian city of Kryvyi Rih, two sources said, in what would be the first time such a weapon has been fired in the war in nearly a year.

Russia launched ballistic missile attacks on Kyiv and other cities in Ukraine in the early hours Thursday, hours after warning of an attack.
