Jakarta:  Indonesia's police and military are responsible for at least 95 unlawful killings in the easternmost Papua region since 2008, including targeted slayings of activists, Amnesty International said on Monday, condemning a near-total absence of justice for the mainly indigenous victims.

In a report based on two years of research, Amnesty said that more than half the victims were either political activists or people taking part in peaceful protests often unrelated to the Papuan independence movement.

It said none of the killings was the subject of independent criminal investigation. In about a third of the cases, there was not even an internal investigation. When police or military claimed to have investigated internally, they did not make the findings public. Eight deaths were compensated with money or pigs.

The victims are overwhelmingly male indigenous Papuans and the majority are young, aged 30 or under.

The killings - nearly one a month for the past eight years - are a "serious blot" on Indonesia's human rights record, said Usman Hamid, executive director of Amnesty International Indonesia.
