A leading Russian nationalist and daughter of one of Russian President’s top allies was assassinated in a car bomb attack outside Moscow, and the US believes she may have been killed on the orders of elements of the Ukrainian government, The New York Times reported, citing unnamed US officials.

Darya Dugina, 29, was a prominent supporter of the Kremlin’s war in Ukraine and the daughter of Alexsandr Dugin, a far-right proponent of Russian imperialism sometimes referred to as “Putin’s brain” who may have been the intended target of the attack. Dugina was killed in August outside a music and literature festival after stepping into a vehicle that belonged to her father.

Ukraine has denied any involvement in the assassination. But according to The New York Times, the US intelligence community shared an assessment last week that elements of the Ukrainian government likely authorized the attack, echoing the claims of the Russian government. The Times’ sources did not say who might have approved the killing or speak to whether Ukrainian President Volodymyr Zelensky was aware of the plan.

CNN, later on Wednesday, likewise published a report on US officials’ belief that “elements” in Ukraine’s government approved the attack.

Washington played no role in the killing, US officials told the outlets.
