Ukraine said it struck an oil depot and an air-defense radar inside Russia early on November 29 amid an escalation of attacks by both Moscow and Kyiv ahead U.S. President-elect Donald Trump's return to the White House.
Ukraine's military General Staff said a strike on the Atlas oil depot in Russia's Rostov region sparked a fire at the facility, which was previously hit by a similar attack earlier this year.
"Atlas is part of the Russian military-industrial complex, which provides the supply of petroleum products for the army of the Russian Federation," it said in a statement on social media.
It added that a radar station housing a Russian Buk-M3 antiaircraft missile system was destroyed in a separate attack in a Russian-controlled area of Ukraine's southeastern Zaporizhzhya region.
Yury Slyusar, the acting governor of the Rostov region, acknowledged the blaze at an "industrial complex" in the area where the refinery is located, saying more than 100 responders were battling to extinguish the fire.
For the past several months, Russia has been battering Ukrainian cities with increasingly heavy drone, missile, and glide-bomb strikes, causing casualties and damaging energy infrastructure as the cold season settles in.
Ukraine has launched several counterattacks since the administration of U.S. President Joe Biden, the top foreign supporter of Ukraine in its battle against Russia's full-scale invasion, and Kyiv's European allies authorized the use of long-range missiles against targets inside Russia.
During the 2024 presidential campaign, Trump was critical of Biden for pouring billions of dollars into Ukraine to help it fight.
