Authorities say a man under surveillance by terrorism investigators has lunged at officials with a military-style knife and has been fatally shot in Boston.

Police Commissioner William Evans says the man was shot at about 7 a.m. Tuesday at a pharmacy in the city's Roslindale neighborhood and has died.

Evans says the man was under surveillance by the Joint Terrorism Task Force. His name was not made public.

Evans says when a city officer and an FBI agent approached the man to talk to him, he pulled a military-style knife and lunged at them. He says both the officer and FBI agent opened fire.

The man was taken to a hospital, where he died.

Evans says the officer and agent were also taken to the hospital for evaluations.
