Weather Underground Greenwich Village townhouse explosion

On March 6, 1970, an explosion destroyed a three-story townhouse at 18 West 11th Street in Greenwich Village, killing three members of the Weather Underground. The blast occurred as the group was assembling explosives intended for use in planned attacks, and the event exposed the organization’s operational hazards. The explosion prompted federal investigations and marked a turning point in the group’s tactics. The site remains a noted location in accounts of domestic radicalism in New York City.
