Sidarenka died on 24 June 2024 and was buried two days later. He was 48. According to reports, he had committed suicide after he was
interrogated by the
State Security Committee of the Republic of Belarus (KGB) upon his return to Belarus. According to information from the
Belarusian opposition Internet portal
Zerkalo, though, Sidarenka had experienced heavy physical stress in the KGB's
lie detector tests. Belarusian exile media have reported that he killed himself by jumping from a
highrise in Minsk. The Belarusian news outlet
Nasha Niva quoted unnamed sources who said that "[Sidarenka] did not get out of polygraphs and interrogations," further adding that "It is said in Minsk that all career diplomats returning from the
EU are now subject to close operational scrutiny by special services" — that is to say, the KGB. For her part, Katherine Brucker, the Chargée d’Affaires of the
United States Mission, speaking to the OSCE's Permanent Council, said that Sidarenka had died "under circumstances that are unclear and very troubling," and she asserted that there had been "reports" that "his body showed signs of torture." However, no evidence was presented to corroborate these assertions. The Belarusian Foreign Ministry made an announcement about the diplomat's death only after he had been buried, without naming the cause of death. Western media likened the circumstances of Sidarenka's death by
falling out a window to the way in which some earlier critics of Russia and Belarus had died, as well as to
Vladimir Makei's likewise surprising death in 2022. == See also ==
