London stabbings that killed US woman not terrorism, police say

LONDON — A Somali-Norwegian teenager went on a knife rampage through London’s Russell Square, a hub for students and tourists, fatally stabbing an American woman from Florida and wounding five other people.

Police flooded the streets with extra officers and mobilized counterterror detectives before saying the shocking burst of violence appeared to have been “triggered by mental-health issues.”

Police officers used a stun gun to subdue the 19-year-old suspect at the scene of the stabbings late Wednesday, among busy streets lined with hotels close to the British Museum.
