KYIV: Russia launched a score of drones and a missile in an overnight attack that targeted military and critical infrastructure, Ukraine’s air force said on Wednesday, while regional officials said the Kremenchuk oil refinery was hit.

On the Telegram messaging app, the air force said 18 of the 20 Russian-launched kamikaze Shahed drones were destroyed before reaching their targets, as was the missile.

But a repeated target of earlier Russian attacks, the Kremenchuk oil refinery in the central region of Poltava, was struck, setting it ablaze, according to Filip Pronin, head of the region’s military administration. “(The fire) has been extinguished.

The situation is under control,“ he said on Telegram, adding that there were no reports yet of casualties as officials sought to gather more details of the destruction. It was not immediately clear how the refinery was hit.

The refinery, which Pronin said was not operating, has been attacked repeatedly since Russia launched its full-scale invasion of Ukraine 20 months ago.

Reuters could not independently verify the reports.

There was no immediate comment from Russia.
