Ukraine’s Militarnyi website said the site in the village of Kotluban was hit by an overnight drone attack and that the strike had been confirmed by Russian media.

Andriy Kovalenko, head of the Center for Countering Disinformation, a unit of Ukraine’s National Security and Defense Counci, posted on the Telegram app:

“Kotluban, Volgograd Oblast. A depot was attacked of the Main Missile and Artillery Directorate of the Russian Ministry of Defense. Iranian ballistic missiles and launchers were stored there.”

Militarnyi cited locals as saying the depot, situated around 300 kilometers from the Ukrainian border, had been in use since the start of Russia’s war in Ukraine and was a priority target for Kyiv.

Russia said that overnight between Saturday and Sunday, 200 drones were fired at the country of which 125 were shot down. Despite this, Militarnyi said, strategically important targets inside Russia were hit.

The website cited NASA’s FIRMS satellite service, which records forest fires globally and registers sites with high thermal signatures, as confirming that the arms dump was hit.
