Eventually, reports of Belarusian troops in Ukraine started to appear. On 28 February, Belarusian opposition media outlet Charter 97 claimed that some Belarusian soldiers were among the wounded and killed invasion troops in Ukraine, citing anonymous Belarusian and Ukrainian sources.[25] On 1 March, a Ukrainian senior military official said to the public broadcaster Suspilne that Belarusian soldiers had been spotted on the ground in Chernihiv Oblast since 27 February and that they were moving from Horodnia towards Chernihiv, the capital of the northernmost region of Ukraine;[26] however, the Office of the President could not confirm the reports.[27] On 6 March, a Ukrainian presidential adviser, Oleksiy Arestovych, said that the Belarusian army had not taken part in the invasion thus far, stating that earlier claims of Belarusian involvement were based on Russian attempts to project the image of Belarusian aggression. There was no independent confirmation.
I guess it’s still an open question if Belarus had soldiers in Ukraine. I hadn’t heard the final part until rn
