THE United States lamented Cambodia's "poor" human rights record in its annual human rights report Wednesday, citing the abuse of detainees, the impunity of security forces and "endemic" corruption as the areas of most concern. The report is submitted to the US Congress every year, along with 195 other country reports, for foreign policy decisions. "Security forces committed extrajudicial killings and acted with impunity. Detainees were abused, often to extract confessions, and prison conditions were harsh," it says. Embassy spokesman John Johnson said the US was "working with the Cambodian government on most, if not all, of the issues brought up in the report".
