Exclusive: Russia restoring oil refining capacity knocked out by drones

MOSCOW, April 15 (Reuters) - Russia has been able to swiftly repair some of key oil refineries hit by Ukrainian drones, reducing capacity idled by the attacks to about 10% from almost 14% at the end of March, Reuters calculations showed.

Ukraine stepped up drone attacks on Russian energy infrastructure since the start of the year, hitting some major oil refineries across the world's second largest oil exporter in attacks that sent up oil prices.

Russia says the drone attacks amount to terrorism. Ukraine says its drone attacks on Russia are justified because it is fighting for survival as Russia has made "massive retaliatory" strikes on Ukrainian energy infrastructure.

There have been no reports of successful attacks on Russian large refineries since the Taneco plant was hit on April 2.

Russia is repairing its refineries fast, despite difficulties in obtaining Western know-how.
