Aliaksandra Pulinovich was born on February 12, 2007, she lived in Minsk. She was detained on January 12, 2024.

According to a propaganda film shown on state television in late April 2024, Aliaksandra was an active member of the anarchist cell “Black Nightingales,” whose goal was allegedly to carry out sabotage in Belarus and Russia. According to the film, the organization was linked to the “People’s Liberation Army of Ukraine” and the Security Service of Ukraine.

In addition to Aliaksandra Pulinovich, the following individuals were also detained in connection with the Black Nightingales case: Mariya Misyuk, Siarhei Zhyhaliou, Dzmitry Zakharoshko, Anastasia Klimenko, and Trafim Barysau. In the film, some of the detainees talk about their roles, in particular, claiming that they gathered at an apartment in Baranovichi, where they tried to assemble an explosive device, and later planned to test it.

Activists from the Black Nightingales group put up posters and wrote slogans against war and dictatorship, such as “Death to dictatorship,” “A new tsar, a new 1917,” and “Long live Belarus.”

It is known that the anarchists were accused of “preparing an act of terrorism” (Article 13, Part 3, Article 289 of the Criminal Code) and “preparing illegal actions involving firearms and explosives” (Article 13, Part 4, Article 295 of the Criminal Code) committed by an organized group, as well as “desecration of structures” (Article 341 of the Criminal Code).
