WATCH: Home Secretary's statement in Amesbury:
Home Secretary Sajid Javid, on a visit to Wiltshire today, said he wanted to reassure people that both Salisbury and Amesbury were 'open for business.'
He praised the emergency services and local people for their response to the latest incident of Novichok poisoning, which has left two people critically ill in hospital.
He also told reporters there were "no current plans" to impose fresh sanctions on Russia.
He told the Press Association: "We don't want to jump to conclusions.
Mr Javid, who visited the site in Amesbury for around 25 minutes in total, met with Angus Macpherson, the Conservative police and crime commissioner for Wiltshire and Kier Pritchard, the Wiltshire police chief constable.
He also briefly met some residents inside the police cordon, but others said they were disappointed he did not talk with them.
Carol Gibson, who moved into the road around five weeks ago from London, said: "Even if he'd just come over for a minute it would have been nice.
"The MP (John Glen) made the point of coming to speak to us and said these visits are managed for him.
"But the man has a brain as well, he could have come over to say a sentence."
Lucy Pickford, who lives with Ms Gibson, said police had been reassuring overall and had helped put her mind at ease.
She said officers were "approachable" to talk to and had posted leaflets through letterboxes on the new estate.
John Glen, the Conservative MP for Salisbury and South Wiltshire, told the Press Association: "We need to establish quickly what they came into contact with and where.
"The sentiment in the city is frustration, we want to get back to normal.
"We were beginning to recover significantly. It's very very frustrating."
