[Straits Times] A RARE survivor of the Khmer Rouge regime's main jail told on Tuesday how torturers ripped out his toenails and gave him electric shocks to try to make him confess to being a CIA agent. Former mechanic Chum Mey told Cambodia's UN-backed war crimes tribunal how he pleaded for his life as he was tortured for 12 days and nights at the 1975-1979 communist movement's Tuol Sleng detention centre.
