WThe Bombing of Plaza de Mayo was a massacre which took place in Buenos Aires, Argentina, on 16 June 1955. On that day, 30 aircraft from the Argentine Navy and Air Force strafed and bombed Plaza de Mayo square in Buenos Aires, in what remains to this day the largest aerial bombing ever on the Argentine mainland.

WIn 1955, the Prime Minister of South Vietnam Ngô Đình Diệm faced a severe challenge to his rule over South Vietnam from the Bình Xuyên criminal gang and the Cao Đài and Hòa Hảo religious sects. In the Battle of Saigon in April, Diệm's army eliminated the Bình Xuyên as a rival and soon also reduced the power of the sects. The United States, which had been wavering in its support of Diệm before the battle, strongly supported him afterwards. Diệm declined to enter into talks with North Vietnam concerning an election in 1956 to unify the country. Diệm called a national election in October and easily defeated Head of State Bảo Đại, thus becoming President of South Vietnam.
