Alexander has been a journalist for Radio Svaboda since 2004. He previously worked for the German service of state radio. He speaks German and is an expert on Germany and its political ties with Belarus. In August 2020, he was stripped of his accreditation by the Ministry of Foreign Affairs, along with most journalists from foreign media outlets.
On July 16, 2021, Alexander was detained at his parents' home in the Postavy district during mass searches of independent journalists in Minsk and other cities. On July 23 of that year, he was released from the temporary detention facility, remaining a suspect.
On December 15, 2022, the criminal prosecution against the journalist was dropped and the restriction on leaving Belarus was lifted.
