A former Russian spy is in critical condition after coming into contact with an “unknown substance”, British media and sources say, in a case that immediately drew parallels to the poisoning of former Russian agent Alexander Litvinenko.
Skripal was convicted in Russia in 2006 of spying for Britain
He was later freed in Cold War style spy swap
Two victims currently in intensive care
Authorities did not identify the man, saying only that he and a woman were found unconscious on Sunday afternoon on a bench in a shopping mall in Salisbury, an English city about 145 kilometres west of London.
