A mass stabbing in a busy part of London late Wednesday has left an American woman dead and five other people injured. The attack occurred in Russell Square near the British Museum, and authorities have arrested a 19-year-old suspect identified only as a Norwegian national of Somali origin, reports the Guardian. The stabbing comes in the backdrop of terror attacks across Europe, but authorities aren't yet sure about the motive in this case. "All of the work we have done so far increasingly points to this tragic incident as having been triggered by mental health issues," says Mark Rowley of Scotland Yard.
"Indeed at this time we believe it was a spontaneous attack and the victims were selected at random," he says. The identity of the American victim has not been made public. Previously, police said she appeared to be in her 60s. The nationalities of the wounded, none of whom had life-threatening injuries, are American, Australian, Israeli, and British. The stabbings took place about 10:30pm local time, reports NBC News, and police were able to arrest the suspect within minutes.
