Cambodian PM Orders Probe of Activist's Killing Cambodian Prime Minister Hun Sen has set up a committee to probe the death of a prominent environmentalist in a confrontation with military police. Hun Sen's letter establishing the panel, seen Tuesday, said it must make a clear report to him on the death of Chut Wutty. The environmentalist was killed Friday as he accompanied two journalists investigating illegal logging in a protected forest. Military police say an officer shot Chut Wutty after they got into an argument and then killed himself. Hun Sen's letter signed Monday follows calls by Cambodian and international human rights groups for an investigation. Chut Wutty headed Cambodia's National Resources Protection Group. He aggressively exposed logging scandals that sometimes involved official corruption.
