Police cordon off scene of deadly car crash at London school

Police officers cordon off the scene of a crash in southwest London after a car ploughed into the private Study Prep girls' school in Wimbledon, which triggered a major response by emergency services.

An eight-year-old girl was killed and several other children were injured, and the driver being treated by police as terror-related, and the driver -- a woman in her 40s who stopped at the scene -- has been arrested. Police say they are not treating the incident as terror-related. 

She was detained on suspicion of causing death by dangerous driving and was in custody, London's Metropolitan Police said. Sixteen patients were treated on the spot and 10 taken to hospital. There was no immediate word on their ages or condition.
