Four core members of the Khmer Rouge, a communist regime led by the infamous dictator Pol Pot, went on trial at Cambodia's war crimes court on Monday.

The four face charges including genocide, crimes against humanity and war crimes. During the Khmer Rouge's brutal reign, which lasted from 1975 to 1979, up to two million people died from starvation, overwork, torture or execution. The regime ended after Cambodia was invaded by the neighboring country of Vietnam.
