Human rights group Amnesty International is urging Guatemala to account for an estimated 40,000 people who disappeared during the Central American nation's civil war.

Amnesty deputy director Kerrie Howard says Guatemala has not heeded many of the U.N.'s recommendations on reconciliation made 10 years ago.

She is urging lawmakers to approve a commission to investigate the disappearances.

About 6,000 people marched through Guatemala City Wednesday on the 10th anniversary of the U.N. recommendations to demand information on their relatives' whereabouts.

Guatemala's U.S.-backed governments destroyed villages while fighting leftist guerrillas from 1960 to 1996. About 200,000 people, mostly Mayan Indians, vanished or died.
