Russian forces targeted Ukraine’s energy and gas infrastructure in a “massive” night time missile attack and Ukrainian drones struck an important oil refinery inside Russia, officials said, as the almost three-year war rumbled on against a backdrop of renewed diplomatic efforts to end it.

Ukraine’s state energy company, Ukrenergo, said it imposed emergency blackouts due to the Russian attack.
