UK: two people in hospital after exposure to unknown substance Two people are in a critical condition in a Salisbury hospital after being exposed to an "unknown substance" not far from where former Russian spy Sergei Skripal and his daughter were poisoned. The two people, a man and a woman both in their 40s, were discovered unconscious on Saturday June 30 at a house in the village of Amesbury, which is around 12 kilometres (eight miles) from Salisbury.
