Belarusian strongman Alexander Lukashenko said Tuesday that long-standing tensions between Moscow's army and the Wagner mercenary group, which staged a mutiny in Russia, had been mismanaged, according to AFP.

Lukashenko was speaking three days after he had brokered a deal to end the rebellion that rattled his Russian ally Vladimir Putin.

The feud between Wagner and the Russian army had escalated for months, with mercenary chief Yevgeny Prigozhin making increasingly scathing statements against generals.

"We missed the situation, and then we thought that it would resolve itself, but it did not resolve," Lukashenko said.

"Two people who fought at the front clashed, there are no heroes in this case," he added, in an apparent reference to the Wagner chief who rebelled, Yevgeny Prigozhin, and his rival Defence Minister Sergei Shoigu.

The jab implied that Putin -- seen as a mediator between competing Russian factions -- had also not dealt with the conflict well or on time.

Observers have said that some of Russia's "siloviki" -- members of Russia's security apparatus and those close to them -- would also be unhappy with Putin for not dealing with the conflict quickly enough.

Lukashenko said he had ordered his army to be "combat ready" during the uprising in Russia.

"I gave all the orders to bring the army to full combat readiness."

And the Moscow ally said that if Russia "collapsed" then "we would all die," while warning that the West would "take advantage" of any "turmoil."

Under the deal mediated by Lukashenko, Prigozhin is expected to move to Belarus. But the Belarus strongman did not disclose Prigozhin's location.

Putin said Monday that Wagner fighters would also be given the opportunity to go to Belarus, or to join the regular Russian army.
