SAO PAULO (AP) — A federal judge has ordered Brazilian mining company Vale to suspend its planned expansion of a rail line in northern Brazil because it would endanger the livelihood of an Indian tribe living in the region.

The planned double tracking of the Carajas railroad line “could result in serious damage to protected areas and to the traditional lifestyles of the Awa Guaja tribe,” Judge Ricardo Macieira said in his ruling that was posted Thursday on the court’s website.
