US polices forces have shot down a “terror suspect” who was under 24-hour surveillance.
Identified as 26-year-old Usaama Rahim, the man was shot down by an FBI agent as well as a state police officer in a CVS Pharmacy parking lot in a Boston suburb on Tuesday.
The cops approached the suspect who started waving a large military knife at them, according to US Joint Terrorism Task Force Police Commissioner William B. Evans.
"He was someone we were watching for quite a time," Evans said. "The level of alarm brought us to question him today. I don't think anybody expected the reaction we got out of him."
The cops initially approached the man due to a change in his behavior that included some threats he had published on social media against the US police.
"Unfortunately, he came at the officers and, you know, they do what they were trained to do and, unfortunately, they had to take a life," Evans said.
Police later released an image (seen below) of the military knife Rahim allegedly tried to use against the officers.

According to his brother Ibrahim, who is an imam at the Lighthouse Mosque in Oakland, California, Usaama was shot three times in the back while speaking to their father at a bus stop.
"His last words to my father who heard the shots were, 'I can't breathe!,' Rahim said on his Facebook page.
Las enforcement authorities said Rahim appeared to have been radicalized by Takfiri terrorists operating in Iraq and Syria but did not provide further details.
According to the Islamic Society of Boston, police and Muslim leaders are set to meet on Wednesday to watch surveillance video of the shooting.
"As religious institutions serving the Boston Muslim community, the Islamic Society of Boston (ISB) and Islamic Society of Boston Cultural Center (ISBCC) leadership are saddened to hear of the shooting of Usaama Rahim," a statement said. "This tragedy has yielded many important questions that merit additional attention and while we cannot expect all questions to be answered our hope is that greater clarity and transparency will bring some peace to our congregation and the Boston community at large."
