Authorities have released surveillance video showing the fatal shooting of a Boston man suspected of plotting to kill police officers.

The video shown Monday at a news conference comes from a restaurant across the street, and the figures shown are blurry. Police and the FBI say it shows officers shooting 26-year-old Usaama Rahim on June 2 in the city's Roslindale neighborhood after they attempted to question him about "terrorist-related information."

Boston's Joint Terrorism Task Force says it had Rahim under 24-hour surveillance and feared an attack could be imminent. Rahim was fatally shot after investigators said he refused to drop a military-style knife.

Rahim's nephew, David Wright, was arrested last week on a charge of conspiracy with intent to obstruct a federal investigation.
