Dugina expressed similar views and had appeared as a commentator on the nationalist TV channel Tsargrad.
"Dasha, like her father, has always been at the forefront of confrontation with the West,” Tsargrad said on Sunday, using the familiar form of her name.
The explosion took place as Dugina was returning from a cultural festival she had attended with her father. Some Russian media reports cited witnesses as saying the vehicle belonged to her father and that he had decided at the last minute to travel in another car.
No suspects were immediately identified. But Denis Pushilin, president of the separatist Donetsk People's Republic that is a focus of Russia's fighting in Ukraine, blamed it on "terrorists of the Ukrainian regime, trying to kill Alexander Dugin."
