 Expanding on the AP 's work , in June 2000 , CBS News reported the existence of a U.S. Air Force memo from July 1950 , in which the operations chief in Korea said that the Air Force was strafing refugee columns approaching U.S. positions . The memo , dated July 25 , the day before the No Gun Ri killings began with such a strafing , said that the U.S. Army had requested the attacks on civilians , and " to date , we have complied with the army 's request " . A U.S. Navy document later emerged , in which pilots from the aircraft carrier USS Valley Forge reported that the Army had told them to attack any groups of more than eight people in South Korea . " Most fighter @-@ bomber pilots regarded Korean civilians in white clothes as enemy troops , " South Korean scholar Taewoo Kim would later conclude after reviewing Air Force mission reports from 1950 .
