A Boston man who was under surveillance by the Joint Terrorism Task Force was shot and killed by an FBI agent on Tuesday.
A senior official who spoke to NBC News said the man has been identified as Usaama Rahim.
Officials said Rahim was approached by the agent near a CVS parking lot early Tuesday morning when he pulled out a large knife. The suspect was shot and killed when he ignored orders to put down the weapon, NBC reported.
