(Tribune News Service) — Ukraine’s military said its special forces struck the Borysoglebsk airfield in Russia’s Voronezh region as Kyiv continues to look for ways to reduce the Kremlin’s ability to conduct airstrikes.

The facility in southwest Russia is the “home base” of the Russian military’s Su-34, Su-35S and Su-30SM fighter jets, the Ukrainian General Staff said on the X platform on Saturday. The strike comes a day after Ukraine was hit by the largest Russian air attack of the war to date.

“A depot with glide bombs, a trainer aircraft and possibly other aircraft were hit,” the General Staff said, adding that final results of the attack are being evaluated.

Bloomberg can’t verify the information independently, and Russia hasn’t commented on the airfield specifically.

Russia’s defense ministry said, however, that the Voronezh region came under heavy attack overnight, with 34 drones shot down. Local media said mobile internet was turned off in the region for a time for security reasons, a move that’s become regular in certain Russian regions over the past few months.

The strike on Borysoglebsk followed other attacks on Russian military airfields, which Kyiv considers legitimate military targets in Russia’s invasion, which is now well into its fourth year.

In June, Ukraine hit several Russian strategic sites, including the Belaya military base deep in eastern Siberia, with drones. Kyiv’s forces also targeted the Borysoglebsk base in 2024.

Ukraine and Russia continued to exchange UAV attacks overnight. Moscow said 94 drones were shot down over 15 regions.

Ukraine said Kremlin forces fired some 322 drones over several regions from Kharkiv in the northeast to Khmelnytskyi in the northwest. Civilian infrastructure was hit in the Kyiv, Kharkiv and Dnipropetrovsk regions, according to authorities, with about a dozen people injured.
