Russian security service accuses Ukraine of Darya Dugina's murder

"The murder of journalist Darya Dugina has been solved, it was prepared by the Ukrainian special services, by a citizen of Ukraine," TASS reported, citing Russia's Federal Security Service (FSB), which named a woman as the perpetrator and said she had fled to Estonia after the attack.

Ukraine has denied any involvement in Dugina's killing, calling the FSB claims fiction.

Dugina, the editor of a Russian disinformation website, died after a bomb planted in a car she was driving went off in the outskirts of Moscow on Saturday evening.

The FSB said that the assailant was a Ukrainian woman who arrived in Russia on July 23 with her young daughter, TASS reported. The pair attended a festival on Saturday near Moscow where Dugina was a guest of honor.

"The criminals used a Mini Cooper car to monitor the journalist," TASS reported, citing the FSB, adding that the woman had rented an apartment in Moscow in the same building where Dugina lived.

After remotely detonating explosives planted in Dugina's Toyota Land Cruiser Prado, the FSB said the woman and her daughter drove through the Pskov region to Estonia, roughly a 12-hour journey.

CNN cannot independently verify the FSB claims cited by the TASS report.

Mykhailo Podolyak, a key adviser to Ukrainian President Volodymyr Zelensky, said on Monday that the FSB accusation was reflective of the "fictional world" in which Russian propaganda thrives.

"Ru-propaganda lives in a fictional world: [Ukrainian] woman and her 12-year-old child were 'assigned' responsible for blowing up the car of propagandist Dugina. Surprisingly, they did not find the 'Estonian visa' on the spot," he said on Twitter.

Dugina's father, Alexander Dugin, is a prominent Russian nationalist credited with being the architect or "spiritual guide" of President Vladimir Putin's invasion of Ukraine.

Both father and daughter have been sanctioned by the United States and the United Kingdom for acting to destabilize Ukraine.

The US Treasury sanctioned Dugina in March as the chief editor for the disinformation website United World International, which it claimed was owned by Putin ally Yevgeny Prigozhin and pushed messages suggesting Ukraine would "perish" if it was admitted to NATO.

Prigozhin, known as "Putin's chef," is believed to be behind the Internet Research Agency (IRA), the notorious Kremlin-linked troll factory accused of meddling in the 2016 US election.

The UK, in a July filing by the Office of Financial Sanctions Implementation, called Dugina a "frequent and high-profile contributor of disinformation in relation to Ukraine and the Russian invasion of Ukraine on various online platforms."

Putin on Monday sent his condolences to Dugina's family, calling her death "a vile, cruel crime."

In a statement published on the Kremlin's Telegram channel, Putin said: "A journalist, scientist, philosopher, war correspondent, she honestly served the people, the Fatherland, she proved by deed what it means to be a patriot of Russia."
