Washington, D.C.—After two years of brutal government repression and destruction of their homeland, the Ngöbe Indians of western Panama won a major victory yesterday as the Inter-American Commission on Human Rights called on Panama to suspend all work on a hydroelectric dam that threatens the Ngöbe homeland. The Chan-75 Dam is being built across the Changuinola River by the government of Panama and a subsidiary of the Virginia-based energy giant AES Corporation.
