"Police were called by the ambulance service to Prezzo, High Street, Salisbury at 6.45 pm today following a medical incident involving two people — a man and a woman," a Wiltshire Police statement was quoted by Reuters. "As a precautionary measure, the restaurant and surrounding roads have been cordoned off while officers attend the scene and establish the circumstances surrounding what led them to become ill," Wiltshire Police said.
According to the SkyNews broadcaster, four ambulances and a hazardous area response team were dispatched to the scene of the incident. Later the broadcaster reported, citing Western Ambulance Service, that the people affected were conscious and were being provided with medical assistance at the scene.
The restaurant's diners were reportedly asked to provide their blood samples to Salisbury Hospital.
Former Russian military intelligence officer Sergei Skripal and his daughter Yulia were poisoned with what London claimed was an A234 nerve agent in Salisbury in early March.
On July 4, two people were poisoned in the city of Amesbury, allegedly with the same nerve agent, which left one UK woman dead. UK authorities have accused Russia of orchestrating the attacks, but Moscow has repeatedly denied any involvement.
On Thursday, the RT broadcaster released an interview with Petrov and Boshirov, alleged Skripal poisoining suspects, in which the men refuted any involvement in the Skripal case, saying that they had no relation to the GRU service and had been visiting the United Kingdom as tourists.
Boshirov and Petrov emphasized in their interview that they were middle-level businessmen working in the area of sports supplements, not intelligence officers as claimed by London. The two individuals insisted that they visited Salisbury in March to visit local tourist sites.
UK Minister of State for Europe and the Americas Alan Duncan said Friday that the UK would seek a speedy implementation of the EU sanctions against Russia related to the alleged use of chemical weapons and would also strive for further strengthening of anti-Moscow stance.
