Several people have been stabbed in Streatham, south London, and a man has been shot dead by police, in what they describe as a “terrorist-related” incident.
Images on social media show a person face down on the ground outside Boots, with a police officer holding a gun next to a black BMW.
The person on the floor appears motionless.
Sky’s home affairs correspondent Mark White said other photos appear to show him wearing something resembling a suicide vest.
Video shows plain-clothed armed officers approaching the body on Streatham High Road, before quickly pulling back.
Metropolitan Police confirmed the man had died in the incident at around 2pm.
The force tweeted: “A man has been shot by armed officers in Streatham. At this stage it is believed a number of people have been stabbed.
“The circumstances are being assessed; the incident has been declared as terrorist-related.”
