Security Service of Ukraine (SBU) drones struck a Russian radio electronics plant in the western city of Penza that manufactures military-grade equipment, APA reports citing the Kyiv Independent.
"At least 11 explosions were recorded" following a large-scale fire at the JSC Radiozavod plant, a sanctioned facility owned by the Russian state-owned Rostec defense corporation, the source claimed.
The statement comes after Russian officials and media reported mass Ukrainian strikes across multiple regions overnight on July 31, including against an industrial facility in Penza and energy infrastructure in Volgograd Oblast.
Andrii Kovalenko, head of Ukraine's Center for Countering Disinformation, said the Radiozavod plant specializes in equipment for mobile command units, automated combat control systems, and military-grade radio stations.
"It is a key enterprise of the Russian military-industrial complex," Kovalenko said.
