KIÊN GIANG — In just three years under the genocidal Khmer Rouge regime, spearheaded by the Pol Pot, Cambodia was pushed to the brink of extinction with nearly three million people killed.
Not only that, shortly after the two sides of Việt Nam reunified in April 30, 1975 after 20 years of a devastating war, Pol Pot’s army waged terror in the southwestern border area of Việt Nam, committing bloody purges on innocent Vietnamese people.
On May 3, 1975, Pol Pot’s army took over the Phú Quốc Island in the Mekong Delta Province of Kiên Giang. One week later, they invaded Thổ Chu Island and massacred 500 people.
