"Le Monde" reported in December 2019, citing French intelligence contacts, that 15 agents connected with Unit 29155 visited the Haute-Savoie region of the French Alps between 2014 and 2018 including Alexander Petrov and Ruslan Boshirov who are believed responsible for the Skripal poisoning. High-ranking GRU officer Denis Vyacheslavovich Sergeev (alias Sergei Fedotov) has been identified by British authorities as the commander of the team that poisoned Sergei Skripal, a former Russian military officer and double agent for the British intelligence agencies, and his daughter Yulia Skripal. Anatoliy Chepiga, one of the suspected Skripal attackers, was photographed at Averyanov's daughter's wedding in 2017.
