Most of humans rights abuses by Venezuelan security forces in 2006 remained unpunished, according to a report disclosed Wednesday by Amnesty International (AI).

"Human rights violations, including torture, extrajudicial executions and enforced disappearances perpetrated by members of the security forces remained unpunished."

Amnesty International made particular reference to the case of eight people, including two children, who were found in a ranch in the villages of La Victoria and El Nula in Alto Apure region, on the border with Colombia, last July 2006.

"Witness accounts and initial evidence obtained by the police indicated that several members of the military had been involved in the killings," the report stated.

As quoted by AFP, the organization pointed also to the cases of Melquíades Villarroel and the Mendoza family, threatened after a judge sentenced five police officers for the killing of their relatives.

The AI report noted that "human rights defenders and journalists continued to be threatened and intimidated."
