On 7 September 1986, after months of planning, the FPMR attacked Dictator Augusto Pinochet's car in an assassination attempt. Five of Pinochet's bodyguards were killed and eleven wounded. Pinochet, however, only suffered minor injuries. He was riding the car with his then 10-year-old grandson who survived unharmed. Also in 1986, Chilean security forces caught the FPMR smuggling an 80-ton shipment of weapons in Carrizal Bajo, including C-4 plastic explosives, RPG-7 and M72 LAW rocket launchers as well as more than three thousand M-16 rifles.
