    Massachusetts Insitute of Technology went into lockdown Thursday night when an MIT police officer was shot and killed in an incident related to the operation against the Boston marathon bombing suspects. The officer died shortly after being taken to Massachusetts General Hospital. An hour later, in nearby Watertown, two suspects engaged officers with heavy automatic gun fire, and threw what appeared to be hand grenades from the car windows. The chase left one officer injured and taken to Beth Israel Hospital. One suspect was reported to be injured and in custody, with another reportedly at large. Officers at the scene were joined by the FBI, SWAT teams, and bomb-diffusing robots.
