The New York Times reported, citing U.S. officials, that U.S. intelligence agencies believe parties in the Ukrainian government allowed the murder of Daria Dugin, the daughter of Kremlin-connected intellectual Alexander Dugin, last August.

U.S. officials told the New York Times that Washington did not participate in the attack by providing intelligence or any other assistance.

These officials said they had no prior knowledge of the operation and made it clear that they would have opposed the assassination had they been consulted on the matter, blaming Ukrainian officials for the assassination.

Ukrainian authorities denied involvement in the assassination immediately after the Dogina attack, and senior officials confirmed that denial when asked about the US intelligence assessment that pointed to Ukrainian complicity.

According to the New York Times, US officials are frustrated by the lack of transparency in Ukraine’s military and secret plans, especially in Russia.
