The head of Russia's Wagner mercenary force warned that Russia's position around the eastern Ukrainian city of Bakhmut was in peril unless his troops got ammunition, the latest sign of tension between the Kremlin and the private militia chief.
Ednews reports citing Reuters that Ukrainian military officials and analysts also reported leaders of Russia's 155th Brigade fighting near the town of Vuhledar, south of Bakhmut, were resisting orders to attack after sustaining severe losses in attempts to capture it.
For its part, the Russian Defence Ministry on Sunday said Russian forces had hit a command centre of the Ukrainian Azov Regiment in southeastern Zaporizhzhia region. The ministry did not elaborate on the attack.
Reuters could not independently verify the battlefield accounts.
Wagner chief Yevgeny Prigozhin said Russia's front lines near Bakhmut could collapse if his forces did not receive the ammunition promised by Moscow in February.
"For now, we are trying to figure out the reason: is it just ordinary bureaucracy or a betrayal," Prigozhin, referring to the absence of ammunition, said in his press service Telegram channel on Sunday.
The mercenary chief regularly criticises Russia's defence chiefs and top generals. Last month, he accused Defence Minister Sergei Shoigu and others of "treason" for withholding supplies of munitions to his men.
In a nearly four-minute video published on the Wagner Orchestra Telegram channel on Saturday, Prigozhin said his troops were worried that the government wanted to set them up as possible scapegoats if Russia lost the war.
"If Wagner retreats from Bakhmut now, the whole front will collapse," Prigozhin said. "The situation will not be sweet for all military formations protecting Russian interests."
