The name of the second suspect in the Salisbury case is actually Alexander Mishkin, the BBC understands. 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.
British prosecutors named two Russian men, believed to be officers in Russia's intelligence service, they believe were behind the nerve agent attack on a former Russian spy and his daughter in the U.K. earlier this year. They named the men as Alexander Petrov and Ruslan Boshirov, and said they are officers in Russia's foreign military intelligence agency, the GRU.
