The company noted that the aggressor hit civilian sites critical for gas delivery during the heating season.
"The attacked facilities have no military significance," Koretskyi said.
“These manic terrorist strikes serve one purpose — to deprive Ukrainians of gas, heat, and light.”
The company said the Russian attack caused hits and destruction. Cleanup and damage assessments are underway at the sites.
Russians also damaged equipment at Zaporizhzhyaoblenergo, leading to outages for consumers in the regional center and Zaporizhzhya district, the Energy Ministry said. Difficult situations persist in Sumy and Chernihiv oblasts, with scheduled hourly power cuts.
Regional governor Ivan Fedorov earlier reported over 73,000 subscribers without power from the overnight strike.
Mass attack on Ukraine on Oct. 5
Russia began another assault on the evening of Oct. 4, launching several waves of drones. Overnight into Oct. 5, Ukraine's Air Force detected the takeoff of Tu-95 strategic bombers and MiG-31K fighters, which fired Kinzhal and Kh-101 missiles.
Most of the air targets were headed towards the western regions, in particular Lviv Oblast. This was the largest attack on the region since the start of the full-scale war.
A family of four was killed as a result of the Russian attack on Lviv Oblast.
In addition, Russian troops carried out a combined attack on the city of Zaporizhzhya, using strike drones and guided aerial bombs. The city experienced power and water supply interruptions, as well as a fire at one of the enterprises. One person was killed.
Ukrainian President Volodymyr Zelenskyy said that Russia had used more than 50 missiles and about 500 strike drones. The regions of Ivano-Frankivsk, Chernihiv, Sumy, Kharkiv, Kherson, Odesa, and Kirovohrad were targeted.
