British counter-terrorism police said on Friday they believed they had found the source of the Novichok nerve agent that killed a woman in southwest England and left her partner critically ill in hospital. Dawn Sturgess, 44, died this month, just over a week after she was exposed to Novichok near the city of Salisbury where Russian double agent Sergei Skripal and his daughter Yulia were struck down with the same poison in March. Sturgess’ partner, 45-year-old Charlie Rowley from Amesbury, a town a few miles from Salisbury, is now recovering in hospital.
