Retaliatory strikes

- The Russian Defense Ministry has reported a massive strike with long-range precision weapons and drones on key facilities in the Ukrainian energy sector and military industry, as well as railway junctions, arsenals and locations where Ukrainian military personnel and foreign mercenaries are deployed. The ministry emphasized that "all the goals of the massive strike have been achieved."

- According to the ministry, production operations have been disrupted at Ukrainian enterprises engaged in making and repairing military equipment and ammunition. In addition, foreign military equipment and ordnance delivered by NATO countries were destroyed, transfers and rotations of Ukrainian reserves were disrupted, and military units "in areas where combat capability was restored" were hit.

- Ukrhydroenergo Director Igor Sirota called the scale of the damage "very large," but said it would be difficult to estimate how long it would take to eliminate the consequences. He gave assurances, however, that there was no threat of a dam breach.
