Ukrainian forces have struck a headquarters of Russia's Wagner mercenary group in eastern Ukraine, Luhansk's Ukrainian governor has said.

Serhiy Haidai said a hotel where the group was based in Kadiivka, Luhansk region, was hit. He added there were major Russian losses.

The BBC was unable to independently verify Wagner's presence at the hotel.

Wagner are state-sponsored mercenaries who act in the Kremlin's interests, according to Western experts.

The private military company, set up by Yevgeny Prigozhin, a former restaurateur and close associate of Russian President Vladimir Putin, has repeatedly been accused of war crimes and human rights abuses.

Wagner units have previously been deployed in Crimea, Syria, Libya, Mali and the Central African Republic.

In the Kadiivka strike, Mr Haidai said Russia had suffered "significant losses" and he expected "at least 50%" of the surviving forces to die due to a lack of medical treatment."
