Ukraine has not come close to exhausting its capacity to fight Russia, Wagner chief Yevgeny Prigozhin said in an interview with Danish media on Tuesday.

"Any offensive must be evaluated, as well as its results, after the enemy's offensive potential has been exhausted. As far as I understand, Ukraine's offensive potential is far, far from exhausted," he said.The boss of Russian private military company also said he doesn’t know if his force will remain in Ukraine amid a dispute with Russia’s Defense Ministry over contracts.

It comes after the Russian Ministry of Defense announced Saturday that “volunteer units” and private military groups would be required to sign a contract with the ministry, which would “give the voluntary formations the necessary legal status” and create “unified approaches” to their work.

The order did not name the Wagner group, but the move is seen a way of controlling the influential military force. Prigozhin – who has publicly feuded with defense leaders – said the move did not apply to Wagner.
