Ukraine's armies ready to fight
The extent of damage to the military base of the group - which has been linked to war crimes - is not clear.
Luhansk's governor claims its secret location was revealed after a Russian journalist shared its address.
Last week, pro-Kremlin correspondent Sergei Sreda posted a photo on Telegram of the base with its apparent address.
The image, shared on the social media site but since deleted, shows five people in military uniform with a street sign in Popasna, Luhansk visible in the top left corner.
While the BBC has not been able to confirm the connection between the photo and the strike, Governor Serhiy Hayday wrote on Telegram 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".
The Wagner 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.
