Skripal Attack: Second Russian Salisbury Suspect Named bbc.com

The Bellingcat investigative website says the man who travelled under the alias Alexander Petrov is in reality a military doctor working for Russian intelligence, the GRU.

Last month, Bellingcat named the first suspect as Anatoliy Chepiga, a claim rejected by Russia.

More details about how it uncovered the identity will be released on Tuesday.
