New York -
Tuesday called for Cambodia's courts to deliver a verdict on the mass killings in the 1970s by the country's Khmer Rouge government, whose leader Pol Pot died 10 years ago.
Pol Pot led communist troops to topple the US-backed government in Phnom Penh in April, 1975, and launched a country-wide sweep to wipe pout the middle class and intellectuals, resulting in more than 2 million deaths from forced labour and extermination.
