Moscow, Aug 26 (IANS): Russian President Vladimir Putin's troops have been filmed writing the message 'For Darya Dugina' on shells and grenades before firing a volley of the munitions at Ukrainian forces, the media reported.

Russian soldiers in the Donetsk region of eastern Ukraine wrote on the ammunition that this was their 'revenge' for Dugina, 29, the daughter of Putin's Rasputin-esque 'guru' advisor who was killed in a car bombing at the weekend, the Daily Mail reported.

Dugina, whose father Alexander Dugin is a notorious ultranationalist, died in an explosion on a motorway near the village of Bolshiye Vyazyomy just outside the capital on Saturday night.

The Kremlin quickly announced the culprit behind the bombing, believed to be intended for Dugin instead, as 43-year-old Ukrainian mother and alleged spy Natalia Shaban-Vovk.

But Ukrainian and Western officials, as well as a number of prominent Russian commentators, believe the car bomb was a 'false flag' operation by pro-Kremlin forces in order to frame Ukraine and provide a justification for a further escalation of violence.

Video shows Russian forces from the Sparta Battalion in the puppet state of Donetsk People's Republic in eastern Ukraine writing 'For Darya Dugina', 'RIP Darya Dugina' and 'RIP girl, we'll avenge you' on shells and grenades, Daily Mail reported.

The soldiers are then seen firing the ammunition towards Ukrainian forces. A caption to a video running on Russian pro-war web channels reads: 'For Darya Dugina - fire!'

Another reads: 'This is what we've been warning you about. The Nazis will have to long hear Darya's name as messages from our guys fly towards them. 'You will be punished for this crime, dear neighbours.'
