A man who was under anti-terror police surveillance has been shot dead in a car park in Boston.

Police say he attacked officers with a large knife after being approached by a Boston police officer and an FBI agent.

The shooting took place on June 2 outside a CVS pharmacy in the residential Roslindale neighborhood of Boston.

Officials have not yet released the man’s identity or the reason he was under surveillance.

Boston Police Commissioner William B Evans told the Boston Globe newspaper: “Our officers tried their best to get him to put down the knife.

“Unfortunately, they had to take a life.”
