Brazil's government says more than 100 protesting Indians are expected to abandon the offices of the federal indigenous affairs agency and return to their villages Wednesday.

The chief administrative officer of the Brazilian presidency says 140 Mundurucu Indians occupied the offices of Funai on Monday to protest the construction of a huge hydroelectric dam in the Amazon rainforest.

Gilberto Carvalho says the government will ask a court to issue an eviction notice if the Indians refuse to leave.

The government has said the Belo Monte dam will be a source of clean, renewable energy, and says damage to the environment will be minimized.

But environmentalists and indigenous groups say the dam would devastate wildlife and the livelihoods of 40,000 people who live in the area to be flooded.
