Brazil's Defense Ministry launched Monday a medical care operation for Indian tribes living in the Amazon region, who will be provided with vaccinations, medicines, attention by specialists and food baskets, authorities said.

The goal of the operation dubbed Curumin 2, in which doctors and troops of the three armed forces together with Health Ministry agents will take part, is to provide medical attention to some 17,500 Indians living in remote villages in the vast Amazon region.

The military will have the support of battalions of engineers, who will analyze the works needed to improve the living quarters, drinking-water supplies and communications among the villages, the Defense Ministry said in a communique.

The operation will be carried out over the next 30 days, during which time authorities estimate that some 15 indigenous communities will be visited. EFE
