Chechen fighters criticize Wagner mercenary chief and threaten showdown.

Adam Delimkhanov, a close ally of Chechen leader Ramzan Kadyrov, publicly criticized Yevgeny Prigozhin, Russia's most prominent mercenary, in a video message, calling him a blogger who yells all the time about problems. This drew a stern rebuke from a top Wagner fighter, Dmitry Utkin. Kadyrov had supported some of Prigozhin's criticism of Russia's top military brass last year, but their relations have distanced in recent months.
