American intelligence believes that the Kiev government is behind the murder of Darya Dugina, daughter of the Russian ultra-nationalist philosopher Alexander Dugin killed in an attack in August.
This was revealed by informed sources to the New York Times, stating that the US "did not take part in the attack, neither providing information or other forms of assistance".
Officials also report that US intelligence was unaware of the operation and would have objected if they were consulted.
American officials who spoke to the New York Times did not disclose which elements of the Ukrainian government were behind the murder of the Dugina or whether President Voldymyr Zelensky was aware.
Some also believe that the real target of the attack was the father.
The ultranationalist Dugin has been urging Moscow for months to intensify its war against Ukraine and has always been one of the main supporters of an aggressive and imperialist Russia.
Asked by the prestigious American newspaper, Zelensky's adviser, Mykhailo Podolyak, reiterated that the government of Kiev is not involved in the death of the ultranationalist's daughter.
"In wartime every murder must have a meaning, satisfy a specific purpose, tactical or strategic. Dugina is neither a tactical nor a target.
