A Ukrainian drone strike in Russia's Ryazan Oblast the morning of July 29 targeted a Wildberries warehouse and one of the country's biggest oil refineries.

Axar.az reports, citing The Kyiv Independent, that the reports come amid a sustained Ukrainian strike campaign against the Russian e-commerce giant Wildberries, which has been hard hit by a string of consecutive attacks against its facilities over the past week.

Ukraine targeted the city of Ryazan with a "massive" attack in the early hours of July 29, according to regional Governor Pavel Malkov.

"Ryazan is experiencing a massive drone attack, and air defense systems are engaged. A fire has broken out on the territory of one of the enterprises," Malkov reported.

Emergency services are at work at the attack scene, the governor said. Later, he updated his report to include "fires in industrial areas" and said that six people had been hospitalized with non-life-threatening injuries.
