The Double Seven Day Scuffle was a physical altercation on July 7, 1963, in Saigon, South Vietnam. The secret police of Ngô Đình Nhu—the brother of President Ngô Đình Diệm—attacked a group of US journalists who were covering protests held by Buddhists on the ninth anniversary of Diệm's rise to power. Peter Arnett of the Associated Press (AP) was punched on the nose, and the quarrel quickly ended after David Halberstam of "The New York Times", being much taller than Nhu's men, counterattacked and caused the secret police to retreat. Arnett and his colleague, the Pulitzer Prize-winning journalist and photographer Malcolm Browne, were later accosted by policemen at their office and taken away for questioning on suspicion of attacking policemen.
