Indonesia's human rights commission said on Wednesday it had found evidence of human rights violations after a mud volcano in East Java started erupting in 2006 displacing more than 50,000 people. The commission...said it could bring a case to the country's human rights court. It said that it would establish a special team to investigate further and violations could involve the state and private firms. Some scientists have said that energy firm PT Lapindo Brantas' [joint venture Energi Mega Persada, MedcoEnergi, Santos] drilling for a gas exploration well set off the mud volcano. Lapindo has denied it is to blame, saying the mud disaster was triggered by tectonic activity. The human rights commission said it did not see a strong possibility that it was triggered by natural causes.
