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.

On the night of February 11, the Russian army launched 124 strike drones and up to 18 cruise missiles at Ukraine. Aviation was involved in repelling Russia's air attack, according to the Ukrainian Air Force.

Russian forces carried out a coordinated strike, using a mix of missile types targeting gas extraction infrastructure in Poltava Oblast - this overnight attack marks one of the largest air assaults in recent weeks,
