Russia struck the Kremenchuk oil refinery in the central Poltava region of Ukraine in an overnight drone attack, causing a fire, governor Dmytro Lunin said on Wednesday.

Refinery operations have been temporarily stopped, he said on the Telegram messaging app, adding that there was no information about casualties.

“Last night, Russians repeatedly attacked the Poltava region. Our air defence system did a good job against enemy UAVs (unmanned aerial vehicles),” he said. The refinery has been attacked repeatedly by Russia since it invaded Ukraine last year.

Ukraine’s air defence systems shot down 17 out of 24 drones that Russia launched on Ukraine overnight, the military said. Reuters could not independently verify the report.

Drones destroyed

Russia’s air defence systems destroyed Ukraine-launched drones over the Belgorod and Oryol regions late on Monday, the Russian defence ministry said, with local officials saying that there was no destruction or casualties.

The ministry, in posts on the Telegram messaging platform, said that two drones were destroyed over the Oryol region in Russia’s southwest and one over the Belgorod region, which borders Ukraine.

Governors of both of the regions said there was no destruction or casualties. Reuters could not independently verify the reports. There was no comment from Ukraine.
