Who is behind the killing of Vladlem Tatarsky?

Christo Grozev from the renowned investigative reporting website Bellingcat has been speaking to Sky News about Vladlem Tatarsky.

He says the Russian blogger was known for some "extremely radical statements".

These included disparaging the official Russian military forces and praising the Wagner Group mercenaries, Mr Grozev said.
He added it is important to remember that Tatarsky was a soldier who participated in the 2014 invasion of Ukraine, not just a blogger.

Discussing the blast, Mr Grozev added: "At this point nothing is certain. It could well be that this was a Ukrainian operation.
"It might also be an operation of Russian security services as a false flag operation to consolidate the pro-war sentiments in Russia."
