(CBN) British police now say a total of roughly 21 people have sought treatment after a nerve agent was used to attack an ex-Russian spy and his daughter.

Wiltshire acting police chief Kier Pritchard told Sky News on Thursday that “a number” of those people got blood tests, support and hospital advice.

He says only three people remain hospitalized. They are former agent Sergei Skripal, his daughter Yulia and police Sgt. Nick Bailey.
