Naftogaz Group, Ukraine's largest national oil and gas company, has to import additional gas volumes following a large-scale combined Russian attack on its gas production facilities on 5 May. Source: Serhii Koretskyi, CEO of Naftogaz of Ukraine, during the national joint 24/7 newscast, as reported by Interfax-Ukraine, a Ukrainian news agency Quote: "Sadly, ballistic missiles have caused severe damage… There have certainly been gas losses. Of course, we will make up for them and restore production. We will rebuild everything and do everything necessary. We will compensate for temporary losses in domestic production with imported volumes, as we did last year." Details: Koretskyi said that since the beginning of 2026, Russia has carried out 107 large-scale combined attacks on Naftogaz Group facilities, mostly gas production sites. The latest attacks have continued for five days in a row. He also reported that Naftogaz will soon restore gas supply to consumers left without supplies as a result of the attack. Media reports say 3,500 consumers are without gas. Koretskyi also expressed his condolences over the deaths of three Naftogaz employees and two State Emergency Service (SES) workers who were killed in the attack. After the all-clear was sounded, they returned to the facility to deal with the aftermath of the attack, but Russia launched a second strike using ballistic missiles. He said most of those injured are in hospital, although some have already been discharged. Background: On the night of 4-5 May, three Naftogaz employees and two SES workers were killed in a Russian attack on Naftogaz facilities. Another 37 people were injured. Earlier, Vitalii Diakivnych, Head of Poltava Oblast Military Administration, reported that four people had been killed and 31 injured in a combined Russian strike on Poltava Oblast on the night of 4-5 May. Two firefighters were killed and 23 injured in a Russian double-tap missile strike on a facility in Poltava Oblast, where they were extinguishing a large fire caused by an earlier attack. The intensity of attacks on Naftogaz infrastructure is increasing. On 4 May alone, Russian forces struck five facilities of the group in Sumy and Kharkiv oblasts, causing fires at the sites.
