The FSB claims a Ukrainian woman rented a flat in Ms Dugina’s building, trailed her, planted the car bomb and then escaped to Estonia. Ukraine, however, continues to deny any involvement in the assassination. Ms Dugina was the daughter of Aleksander Dugin, an ultranationalist political philosopher.
Many experts believe his views have influenced the Kremlin’s narrative on Ukraine.
His daughter was killed on Saturday night on the outskirts of Moscow, after her car was torn apart by a bomb.
Certainly, eyebrows have been raised at the speed of the investigation by Russian FSB agents.
Lyubov Sobol, a prominent anti-Putin activist, noted how slow Russian security officials had been in prosecuting the murders of prominent Putin critics such as Boris Nemstov.
She tweeted: “I don’t remember other high-profile murders and assassination attempts (Politkovskaya, Nemtsov, Kara-Murza, Navalny) being ‘revealed’ so quickly.”
Russian partisans have claimed responsibility for the murder of Dugina and vowed “to destroy Putin” in a statement.
The National Republican Army, a previously unknown organisation, has now claimed it carried out the bombing in a statement.
Describing themselves as “partisans and fighters”, they wrote: “We declare President Putin a usurper of power and a war criminal.
“We believe that disenfranchised people have the right to rebel against tyrants.
“Putin will be deposed and destroyed by us!’
