Ukrainian artillery has struck a headquarters of Russia’s shadowy Wagner paramilitary group of mercenaries in eastern Ukraine, reports say.
The attack in Popasna was reported by Serhiy Hayday, Ukrainian governor of Luhansk region, and several pro-Kremlin war reporters.
The number of casualties is not clear and details remain sketchy. Photos said to show the damage were posted on the Telegram messaging service.
Wagner has been linked to war crimes.
The group was deployed to Crimea and Ukraine’s Donbas region in 2014, when Kremlin-backed forces ousted Ukrainian troops from areas they later declared to be part of Russia.
Wagner units have also been sent to Syria, Libya, Mali and the Central African Republic.
The Kremlin does not acknowledge Wagner’s existence, but Western intelligence links the group to Yevgeny Prigozhin – nicknamed “Putin’s chef” because his catering business has long helped President Vladimir Putin and the armed forces.
Mr Prigozhin, like many other Russian officials, is under Western sanctions.
Wagner is known as a PMC – private military company. But they are state-sponsored mercenaries who act in the Kremlin’s interests, Western experts say. They have been accused of repeated war crimes and human rights abuses.
On Telegram, Governor Hayday wrote that Ukrainian forces “hit an enemy HQ whose whereabouts were established thanks to a Russian journalist”.
“This time the successful strike destroyed the Wagner PMC HQ in Popasna yesterday,” he said. He added that “the number of dead is being clarified”.
