NAIROBI, Kenya –  An international human rights group says victims of the violence in Kenya that killed more than 1,000 people and displaced more than 600,000 from their homes six years ago are still seeking justice and reparation.

Amnesty International said Tuesday that Kenya’s government and parliament have consistently obstructed efforts to investigate and prosecute those suspected of committing crimes under international law during 2007-08 postelection violence.

The group’s report says an announcement by Kenya’s director of prosecution earlier this year that more than 4,000 cases cannot precede because of insufficient evidence suggests investigations were ineffective.

Kenya was plunged into violence following the disputed election of Mwai Kibaki as president in December 2007 polls. Kibaki’s main challenger, opposition leader Raila Odinga, said the vote was rigged. International observers said it was flawed.
