LONDON — Two British citizens in Amesbury, England were exposed to the same nerve agent that was allegedly used to poison former Russian military intelligence officer Sergei Skripal in March, Scotland Yard’s counter-terrorism chief, Neil Basu, said in a statement on Wednesday.

“Following the detailed analysis of these samples, we can confirm that the man and woman have been exposed to the nerve agent Novichok, which has been identified as the same nerve agent that contaminated both Yulia and Sergei Skripal,” Basu said.

Both man and woman are in hospital in “critical condition.”

However, the counter-terrorism police chief refused to say that the nerve agent “was from the same batch that the Skripals were exposed to,” but did not rule out that these two incidents may be linked.

Some 100 detectives from the Counter Terrorism Policing Network are now investigating the case. TASS
