During the night and morning of June 10, at least three fuel-energy and defense industry facilities in Russia were targeted in attacks.

That is according to the Telegram channel ASTRA, Ukrinform reports.

An OSINT analysis confirmed a strike on the VNIIR-Progress plant in Cheboksary. Local residents reported several air raid alerts and delayed notifications from authorities. ASTRA published several videos from the scene. One shows the first moments after a strike on the facility's administrative building, while another shows smoke rising above the same defense enterprise from a different angle.

The head of Russia's Chuvash Republic, Oleg Nikolayev, confirmed that Cheboksary had come under a missile attack early on June 10, though he did not specify which facilities were affected.

VNIIR-Progress was previously attacked on May 5. The plant manufactures Kometa antennas used by the Russian military to protect drones from Ukrainian electronic warfare systems.
