A wave of drone strikes targeted Russia’s oil refineries and border regions for the second day in a row on Wednesday, with one sparking a fire and injuring several people in the Ryazan region, officials said.
Dozens of drones were launched overnight, with the vast majority shot down, causing some damage but no victims, over the Ukrainian border regions of Belgorod, Bryansk, Kursk and Voronezh, according to regional governors.
One sparked a fire and wounded several people when it crashed into an oil refinery in the Ryazan region that lies some 200 kilometers (120 miles) southeast of Moscow.
“The Ryazan oil refinery was attacked by a drone,” Ryazan regional governor Pavel Malkov wrote on Telegram.
“According to preliminary information, there are injuries,” he wrote.
A fire broke out at the refinery following the strike and “all rescue services are working at the scene,” Malkov said.
A drone targeting another oil refinery in the Leningrad region near the second city of Saint Petersburg in northwest Russia was shot down, Alexander Drozdenko, the regional governor wrote on Telegram, adding there was no damage and no victims.
More than 30 drones were shot down over the Voronezh region, with some light damage reported, regional governor Alexander Gussev wrote on Telegram.
Six drones were shot down over the Belgorod region, damaging several electrical lines and causing power outages, governor Vyacheslav Gladkov wrote on Telegram.
Eight drones were shot down over the Bryansk region and four were destroyed over the region of Kursk without reports of damage, the governors of those regions wrote on Telegram.
On Tuesday, Ukraine launched one of its most significant drone strikes on Russia so far in the two-year conflict.
Two Russian energy sites, including one of the largest oil refineries some 800 kilometers from the border, were hit in the strikes, Russian officials said.
A major oil refinery in Kstovo, just outside the city of Nizhny Novgorod, was hit by a drone early on Tuesday morning, the regional governor said.
Another drone crashed into a fuel depot and started a fire in Oryol, around 160 kilometers from the border, according to the regional governor.
