British police are scouring sections of Salisbury and Amesbury in southwest England, searching for a container feared to be contaminated with traces of the deadly nerve agent Novichok.
More than 100 officers are looking for clues Friday in a race to understand how two local people in Amesbury were exposed to a nerve agent that was produced in the Soviet Union during the Cold War.
Police believe they were somehow exposed to a contaminated container that may have been used in a March nerve agent attack on an ex-Russian spy and his daughter in nearby Salisbury.
The two new victims — Dawn Sturgess, 44, and Charlie Rowley, 45 — are in critical condition.
