Congress mulls diluting protection for indigenous territories

Riot police have fired teargas and rubber bullets at indigenous activists protesting outside Brazil's congress against new legislation that would undermine legal protections for indigenous territories, and open them up to commercial agriculture and mining.

Thick clouds of teargas enveloped the demonstrators, including children and the elderly, as police attempted to clear the camp in Brasilia on Tuesday where they have been protesting for the past two weeks.
