Cambodians seeking Khmer Rouge justice

Cambodians who lost relatives to the Khmer Rouge regime are converging on the capital to hear the trial of the three most senior surviving leaders.

There is anger that only three men are being tried for the deaths of some 1.7 million people in the 1970s.

Only one senior Khmer Rouge figure has ever been convicted, and Pol Pot died in 1998 before facing a full trial for his crimes.
