British police declared a “major incident” on July 4 after two people were found critically ill after allegedly being exposed to an “unknown substance” near the site where former Russian spy Sergei Skripal and his daughter, Yulia, were poisoned months ago.
The incident unfolded near Amesbury, in Wiltshire, England, according to local police, who said the victims are a man and a woman in their 40s who “were found unconscious in a property.”
