Military doctor for Russia's GRU military intelligence unit responsible for Sergei Skripal, says Britain

The second Russian who Britain says was responsible for the poisoning of former double-agent Sergei Skripal was a military doctor for Russia's GRU military intelligence unit, investigative website Bellingcat said on Monday.

Bellingcat said the real name of the man previously known as Alexander Petrov was Alexander Yevgenyevich Mishkin.

"Bellingcat's identification process included multiple open sources, testimony from people familiar with the person, as well as copies of personally identifying documents, including a scanned copy of his passport," the website said.
