国际英语资讯:British couple critically ill after exposure to nerve agent

Basu added: "This is a precautionary measure while we continue to investigate how they came into contact with the substance. I do want to reassure the public that there is no evidence that either the man or woman recently visited any of the sites that were decontaminated following the attempted murders of Sergei and Yulia Skripal."

He said over the coming days people in the area can expect to see an increased police presence, which will include officers wearing protective equipment as they carry out activity at a number of sites.

Last month the heir to the British throne, Prince Charles and his wife the Duchess of Cornwall, visited Salisbury and mingled with shoppers at the local market to reassure people that the city was now safe to visit.

Police have not yet given any clues about how or why the couple were exposed to the nerve agent, but Basu said: "I would add that the complex investigation into the attempted murders of Yulia and Sergei remains ongoing and detectives continue to sift through and assess all the available evidence and are following every possible lead to identify those responsible, for what remains a reckless and barbaric criminal act.

"We are not in a position to say whether the nerve agent was from the same batch that the Skripals were exposed to. The possibility that these two investigations might be linked is clearly a line of enquiry for us," he said.
