She was the daughter of Alexander Dugin, who is often called "Putin's brain." Dugin is a prominent Russian nationalist intellectual

whose vision of a revived Russian empire came to influence Putin's war in neighboring Ukraine.

For over a decade, both father and daughter have advocated for Russia's invasion. They have said many times that Russia can only thrive if Ukraine is destroyed.

Dugin was placed on Western sanctions lists as a key proponent of the Kremlin's forced annexation of Crimea from Ukraine.

He also backed Russia's decisions to send troops into Ukraine earlier this year.

The United States imposed sanctions on his daughter in March after she served as chief editor for United World International

which the Treasury Department classified as a disinformation site. The United Kingdom also placed sanctions against Dugina in July.

Several Dugin allies immediately suggested he was the target of the blast and blamed the Ukrainian government, which denied any role in the incident.
