Belarusian Defence Minister Viktor Khrenin said on Friday that there was a high probability of an armed provocation from neighbouring Ukraine, the state-run Belta news agency reported.
Khrenin's comments came amid an ongoing Ukrainian incursion into Russia that began on Aug. 6 when thousands of Kyiv's troops smashed through Russia's western border.
Belarusian President Alexander Lukashenko, a top ally of Vladimir Putin, warned on Thursday that Ukraine could attack Belarus and widen the war.
