イエン・サリ
In 1952 Pol Pot, Hou Yuon, Ieng Sary, and other leftists gained notoriety by sending an open letter to Sihanouk calling him the "strangler of infant democracy." A year later, the French authorities closed down the KSA. In 1956, however, Hou Yuon and Khieu Samphan helped to establish a new group, the Khmer Students' Union. Inside, the group was still run by the Cercle Marxiste.
