On the night of March 13, a fire broke out in the Kaluga Region on the territory of one of the industrial enterprises, caused by an attack by unmanned aerial vehicles (UAVs). According to regional authorities, the incident affected the Dzerzhinsky District, where a technical building caught fire as a result of falling drone debris. 

Kaluga Region Governor Vladislav Shapsha reported that air defense forces successfully intercepted and destroyed 25 drones over the region's territory. Despite the prompt actions of the air defense, one of the devices still caused a fire at the enterprise. The fire was quickly localized and extinguished, which made it possible to avoid more serious consequences. As a result of the incident, one night shift employee was slightly injured. The victim was immediately given medical assistance; his life and health are not in danger. 

In addition, the attack affected other areas of the region. In particular, in the Khvastovichsky district, the drone debris damaged a communications tower and a power line. Operational groups are working at the drone crash sites to assess the damage and coordinate restoration work. According to preliminary data, casualties and significant destruction of infrastructure were avoided, but the exact extent of the damage has yet to be determined. 

The incident in the Kaluga Region was part of a larger wave of drone attacks recorded on the night of March 13 in several regions of Russia. According to the Russian Defense Ministry, a total of 77 UAVs were intercepted and destroyed in six regions of the country overnight. In addition to the Kaluga Region, the attacks affected the Bryansk, Kursk, Voronezh, Rostov, and Belgorod Regions. In the Bryansk Region, 30 drones were shot down, in the Kursk and Voronezh Regions — six each, and in the Rostov and Belgorod Regions — five each. 

Similar incidents have occurred in the Kaluga region before. For example, in February 2025, a fire was also recorded at an industrial facility in the Dzerzhinsky district after a drone crashed, and in November 2024, an enterprise presumably related to oil refining burned in Kaluga. These cases highlight the increasing intensity of attacks using UAVs on infrastructure facilities in the border and central regions of Russia. 

At the moment, law enforcement agencies and special services continue to investigate the circumstances of the attack, as well as determine which specific enterprises could have been targeted.
