The incident with two people collapsing in the UK town of Amesbury appears to be an "unfortunate after-effect" of the earlier poisoning incident in nearby Salisbury, UK Secretary of State for Health and Social Care Jeremy Hunt said.
"This is what looks like a very unfortunate and, hopefully, not tragic after-effect of that earlier incident. At the moment we are not speculating this was a deliberate murder attempt, but we have to be open-minded on the basis of what the police say," Hunt told the Sky News broadcaster.
The official stressed that this meant the people of Salisbury could "carry on" with their business.
"But I think we have to allow the police to do their work. But the assessment from the chief medical officer is that the risk to the public remains low," Hunt said.

Earlier this day, UK Security Minister Ben Wallace stated that Amesbury poisoning was not linked to the Skripal case.
In March, former Russian spy Sergei Skripal and his daughter Yulia were found unconscious in Salisbury after what UK authorities said was exposure to a military-grade nerve agent.
London blamed the Skripals poisoning on Moscow, which strongly denied any involvement in the incident.
