On Sunday, Ukraine called on Belarus to pull back what it described as significant levels of Belarusian forces and equipment deployed at their common border.
The Ukrainian foreign ministry warned Belarus against making "tragic mistakes" while under pressure from Moscow.
A ministry statement urged the Belarus armed forces "to stop unfriendly actions" and withdraw their troops out of range of the border.
The ministry said Belarus special forces and former Wagner mercenary fighters were among the troops at the border.
Their equipment included tanks, artillery, air defence systems and engineering equipment, located in the Gomel region near Ukraine's northern border.
The statement said Ukraine "has never taken and is not going to take any unfriendly actions against the Belarusian people".
Belarusian President Alexander Lukashenko said on 18 August that Ukraine had stationed more than 120,000 troops at the border with Belarus, and deployed nearly a third of its armed forces along the entire border.
Belarus said that it sent aircraft, air defence forces and armour to its border with Ukraine last Monday.
Ukraine's air force said it had shot down 24 of 26 drones launched from Russia overnight over four regions, according to a statement posted on the Telegram messaging app.
