July 18 (UPI) -- Ukrainian drones hit two Russian warehouses, one near Moscow, and killed at least 8 people Saturday.

President Volodymyr Zelinsky said on X that, "two major logistics facilities were hit -- in the Moscow and Tambov regions, more than [311 miles] and nearly [435 miles] from the front line. The aggressor used them to supply sanctioned components for drone production and navigation equipment. An oil facility was also struck. In addition, Ukrainian mid-range strikes engaged targets in the waters of the Sea of Azov and the Black Sea, and in our temporarily occupied Crimea."

Of those killed, seven were working at a distribution center at Kotovsk in the Tambov region and another was at a similar facility in Elektrostal in the Moscow region, CNN reported. Both facilities were owned by Russian retail company Wildberries. But Ukraine alleges that the warehouses were used in the manufacturing of drones.

Wildberries has been described as the Russian version of Amazon, the BBC reported.
