Alexander Lukashenko’s troops will conduct the drills between September 8 and 14 and will simulate the liberation of captured territory.
Mr Hromov said: “This particular exercise will for the first time cover liberating territory captured by the enemy, and reaching the border in a counter-offensive.
“It’s possible that by ‘lost territory’ they could mean Ukrainian borderlands in Volyn, Rivne, and Zhytomyr oblasts.”
Moscow announced in late July that it would hold the “Vostok” (East) exercise in the east of the country, despite waging a six-month-long war in Ukraine, where it has suffered heavy losses of personnel and equipment.
“They (the West) must understand that if they opt for escalation no helicopters or planes will save them,” Lukashenko was quoted as saying.
“Everything was ready,” he said, referring to the work to modify Belarusian warplanes to carry nuclear weapons.
“It’s not a good idea to escalate things with Belarus because that would be an escalation with the Union State (of Russia and Belarus) which has nuclear weapons.
“If they start to create problems … the response will be immediate.”
