The UK sanctioned 18 officers and three units from Russia's military intelligence agency (GRU) on Friday over their role in a 2022 air strike on a theatre in Ukraine that killed hundreds of civilians.
The Foreign, Commonwealth and Development Office (FCDO) said the targeted GRU personnel were responsible for preparations leading to the bombing of the Mariupol Drama Theatre, where civilians had taken refuge and painted the word "children" outside in large letters hoping to deter attacks.
