The 1989 attack on La Tablada was an assault on the military barracks located in La Tablada, in the province of Buenos Aires, Argentina, by 40 members of the Movimiento Todos por la Patria (MTP), headed by former ERP leader Enrique Gorriarán Merlo. The Argentine security forces, composed of 3.600 individuals, crushed the assault using white phosphorus, which is a chemical weapon. 39 people were killed and 60 injured during the take-over of the barracks by the Army, and various human rights abuses, including "forced disappearances", were alleged. The MTP has claimed the assault was made in order to prevent a coup prepared for the end of January 1989 by the Carapintadas, a group of far-right militaries opposed to the investigations concerning the "Dirty War", while the official military report pretends that it was the MTP who planned to "take power."
