On 16 June 1955, 30 aircraft from the Argentine Navy and Air Force bombed and strafed Plaza de Mayo, the main square of the Argentine capital Buenos Aires. The attack targeted the adjacent Casa Rosada, the seat of government, while a large crowd demonstrated in support of the president, Juan Perón. The strike took place during a day of official public demonstrations to condemn the burning of a national flag allegedly carried out by detractors of Perón during the recent Corpus Christi procession. The military reacted as a result of growing tension between Perón and his actions against the Roman Catholic Church. The action was to be the first step in an eventually aborted coup d'état. The number of identified bodies was put at 308, including six children, making it the deadliest terrorist attack in Argentine history. Some victims could not be identified.

L-R: José Félix Uriburu (1930–1932) • Agustín Pedro Justo (1932–1938) • Roberto Marcelino Ortiz (1938–1940) • Ramón S. Castillo (1940–1943)

The heavy loss of civilian lives and the violence with which the act was carried out has prompted comparisons with the wave of state terrorism during the dictatorship of 1976–1983.
