On the 20th, a passenger car exploded outside Moscow, the Russian capital, killing the daughter of a philosopher who was said to have influenced President Putin's foreign policy.
Authorities have launched an investigation that the vehicle was loaded with explosives.
Russian investigators have announced that journalist Daria, the daughter of Russian philosopher Aleksandr Dugin, has died after a car exploded outside Moscow on the night of the 20th.
Authorities have launched a murder investigation as the car had an explosive device on the driver's side.
Dugin is said to have influenced President Putin's foreign policy, and is also called "Putin's brain" by the Western media.
He is said to be anti-Western and strongly supportive of Russia's invasion of Ukraine, advocating the idea that Russia should make the Eurasian region spanning Europe and Asia its sphere of influence.
Some Russian media reported that Mr. Dugin himself was planning to ride in the passenger car that exploded, and there is also speculation from the Russian side that it may be a crime by Ukraine targeting Mr. Dugin.
Russian Foreign Ministry spokeswoman Zakharova said on social media on the 21st, "If there are traces of Ukraine, it is necessary to discuss the state terrorism policy pursued by the Ukrainian regime."
However, Ukrainian president Podlyak, an adviser to the president, denied that Ukraine was involved.
