Spotlight: Pro-Russian Yanukovych ex-aide killed in Spain
On 21 May, unidentified armed individuals shot dead Andriy Portnov, an ex-deputy chief of staff in charge of overseeing judicial affairs for pro-Russian former Ukrainian President Viktor Yanukovych. The incident took place outside the American School in a suburb of Madrid. During his time working under Yanukovych, Portnov was involved in the adoption of controversial laws enabling repression of the 2014 Euromaidan protesters, as well as interventions against judicial independence.1 Despite this, Portnov successfully fought Ukrainian journalists who labelled him a pro-Russian politician in court.2 After leaving the country illegally in 2022, he reportedly briefly returned to Ukraine to meet with top law enforcement officials for unknown reasons.3
Attacks on Ukrainian officials who collaborated with Russia have been frequent since the start of Ukraine’s full-scale invasion by Russia. This includes the assassinations of ex-member of Parliament (MP) Ilya Kyva in Moscow and ex-MP Oleksyi Kovalov in the Kherson region, the killing of ex-MP Oleksyi Zhuravko during a strike in occupied Kherson city, and the wounding of ex-MP Oleh Tsariov in occupied Crimea. Other notable so-called “collaborators,” such as the oligarch Viktor Medvedchuk, were instead used during prisoner exchanges4 as valuable assets for recovering Ukrainian prisoners of war.
However, at the time of writing, Ukraine has not been implicated in Portnov’s killing, and Ukrainian authorities are cooperating with Spanish investigators.5 While the motives and perpetrators of the shooting are unknown, some theories suggest debt issues6 or a false flag operation by Russian agents to mimic Ukraine’s action.7 It is not the first time that Spain has been the site of a high-profile killing associated with the Ukraine war. In February 2024, two unidentified individuals, likely contracted locally by Russia,8 killed an ex-helicopter pilot in Villajoyosa who had defected from the Russian military.
