Patrons of a pub and restaurant in Salisbury are being urged to wash their clothes and possessions after Russian ex-spy Sergei Skripal and his daughter fell ill in a suspected nerve agent attack.
Public health authorities in the UK are warning that as many as 500 people may have been contaminated with the nerve agent used to attack a former Russian spy last weekend.
Sergei Skripal and his daughter Yulia remain critically ill in hospital after being attacked.
Traces of the toxin have been found at a restaurant and a pub in the city of Salisbury and doctors are now urging people who visited the locations last weekend to thoroughly clean their belongings.
