Incident Summary:

10/30/1983: The U.S. Federal Building, housing the FBI headquarters in Hato Rey, Puerto Rico, was blasted with a bazooka. Specifically, it was a light anti-tank weapon which was made for use by the U.S. Army. No casualties resulted from the attack; however, the blast caused shattered windows and frames, and damage to air conditioners and ceiling as well as minor damage to the U.S. Department of Agriculture nearby. There were at least three perpetrators in the attack. The Macheteros claimed responsibility for the attack in a phone call to the Associated Press in San Juan, at which time the caller expressed the group's support for the people of Grenada and opposition towards the US for the invasion of Grenada. Additionally, the group left communiqués which stated the blast was in protest of the policies of the U.S. and Ronald Reagan, who the Macheteros claim, took advantage of the people of Grenada to reestablish imperialism.
