From Peking, Prince Norodom Sihanouk of Cambodia issues a public call for arms to be used against the Lon Nol government in Phnom Penh and requests the establishment of the National United Front of Kampuchea (FUNK) to unite all opposition factions against Lon Nol. North Vietnam, the National Liberation Front (Viet Cong), and the communist Pathet Lao immediately pledged their support to the new organization.
Earlier in March, Sihanouk had been overthrown in a bloodless coup led by Cambodian Gen. Lon Nol. Between 1970 and 1975, Lon Nol and his army, the Forces Armees Nationale Khmer (FANK), with U.S. support and military aid, fought the Khmer Rouge and Sihanouk’s supporters for control of Cambodia. During the five years of bitter fighting, approximately 10 percent of Cambodia’s 7 million people died. When the U.S. forces departed South Vietnam in 1973, both the Cambodians and South Vietnamese found themselves fighting the communists alone. Without U.S. support, Lon Nol’s forces succumbed to the communists in April 1975. The victorious Khmer Rouge evacuated Phnom Penh and began reordering Cambodian society, which resulted in a killing spree and the notorious “killing fields.” Eventually, hundreds of thousands of Cambodians were murdered or died from exhaustion, hunger, and disease.
