Overnight Ukrainian drone and missile strikes across southern Russia killed one person and struck commercial and industrial sites, regional officials said Tuesday.

Acting Belgorod region Governor Alexander Shuvayev confirmed one death in an attack near the border with Ukraine. He also said that a woman who was hospitalized for her injuries following strikes earlier this month had died.

In the nearby Rostov region, Governor Yury Slyusar said an Ozon warehouse was among several sites damaged during a missile attack on the port city of Taganrog.

Ozon confirmed that it suspended operations at the facility, where it said a fire broke out. No one was hurt, the company said.

Federal investigators launched a criminal probe into terrorism over the attacks on Taganrog, citing damage to Ozon and other residential and agricultural buildings.

Samara region Governor Vyacheslav Fedorishchev said an “industrial facility” was damaged in overnight strikes. Unconfirmed reports said that a fire broke out at the Syzran Oil Refinery.

NASA’s fire monitoring service FIRMS showed an active fire Tuesday morning on the southwestern outskirts of Syzran, where the refinery, which has been attacked multiple times this year, is located.

Russia’s Defense Ministry said it intercepted 222 Ukrainian drones across Russia and annexed Crimea between Monday night and Tuesday morning.

In Ukraine, officials said one person was killed in Russian attacks on Kyiv. Separate attacks on the city of Zaporizhzhia also killed one person.

Two gas stations in Kyiv were damaged in the overnight strikes, the state energy company Naftogaz said.

The attacks targeting energy infrastructure in both Russia and Ukraine came despite an announcement by U.S. Donald Trump earlier in the week that the two warring sides allegedly agreed to pause such attacks.

Trump has sought to blame the surging cost of diesel in the United States on Ukrainian strikes against Russian oil refineries. While those attacks have put pressure on fuel prices both inside Russia and globally, so too has the U.S.-Israeli war against Iran led to major disruptions in energy markets.

Kremlin spokesman Dmitry Peskov told reporters on Tuesday that Trump’s suggestion for a ceasefire on energy sites, which has been repeatedly floated over the past year, was a “very good idea” but alone would not bring down global fuel costs.
