Members of Brazil's indigenous tribes protested in the country's capital on Tuesday, leading to dramatic clashes with riot police some two weeks ahead of the start of the 2014 World Cup.

Dressed in traditional headdress and armed with bows and arrows, the group rallied against legislation they fear will shrink reserves and undermine protection of their ancestral lands.

The indigenous protesters then joined hundreds of Brazilians marching on Brasilia's World Cup stadium in outrage at the huge sums spent on the upcoming soccer tournament, the BBC reports.

Riot police tried to block the march with volleys of tear gas, sparking clashes that left two indigenous protesters injured and one officer speared in the leg with an arrow, according to the Associated Press.

Thousands of Brazilians have joined similar demonstrations across the country over the past year, decrying that the games' hefty price tag would have been better spent on basic public services.
