Russia's intensified attacks on Ukraine
Russia has stepped up attacks on the energy and gas infrastructure in Ukraine in the recent weeks, Reuters reported. Following Russia's attacks, Ukraine has retaliated by striking the Russian oil refineries and pipelines.
From the beginning of the conflict in February, 2022, Russia has continuously targeted critical infrastructure in Ukraine, hitting power facilities during the drone attack in the past 24 hours.
“As soon as the energy workers receive permission from the military and rescue services, they will immediately begin inspecting the equipment and carrying out emergency repair work,” Ukraine's largest power company DTEK said.
