Yevgeny Prigozhin, founder of Russia's Wagner mercenary group, boasted of his forces' prowess on Saturday amid a simmering rivalry with the defence ministry over who should get credit for leading Russia's assault on the Ukrainian town of Soledar.
After months of tension between Prigozhin and the military establishment, the split was laid bare on Friday when the defence ministry claimed the capture of Soledar - which Ukraine disputed - and initially made no mention of Wagner's role in months of brutal fighting for the salt-mining town in Ukraine's east.
