In the early hours of June 2, Russian forces attacked a key gas infrastructure facility belonging in the Kharkiv region, first with drones and later with missiles.

The Naftogaz Group announced this in a statement, Ukrinform reports.

The enemy used a combined attack tactic. The facility was initially struck by drones, and about an hour later Russia launched a second wave of missile strikes.

The company said emergency services are currently working at the site, and the extent of the damage is being assessed. No casualties have been reported.

"This is how Russia is trying to inflict maximum damage not only on infrastructure but also on the people who rescue, repair, and restore it. It was this tactic that led to tragic consequences on May 5, when our colleagues and State Emergency Service rescuers were killed," said Serghii Koretskyi, CEO of Naftogaz of Ukraine.
