Indonesia must step up efforts to investigate serious human rights abuses surrounding the eruption of a "mud volcano" which displaced 36,000 people, the national human rights commission said...The mud volcano...erupted from a well being dug by Lapindo Brantas, an oil and gas company..."This is a problem that we deem serious, where the state has failed to protect and guarantee basic rights of the victims of the incident and has no political will to pressure PT Lapindo Brantas to take their responsibility," [commission investigator] Supriyadhie said.
