“A knife attack in a London subway station on Saturday was being treated as a ‘terrorist incident,’ the police said after they arrested a 29-year-old man suspected of the assault.
A 56-year-old victim sustained serious, but nonlife-threatening injuries, and two others were wounded less seriously at the Leytonstone station in East London. The suspect was detained after officers used a Taser on him.”
