RIO DE JANEIRO: Indigenous protesters armed with bows and arrows clashed on Tuesday (Wednesday in Manila) with police outside Brazil's Congress, leaving the area enveloped in tear gas and leading lawmakers to suspend debate on a controversial land reform bill. Activists said two Indigenous People were hospitalized with severe injuries and a dozen more sustained light injuries in the clashes while the congressional press office said at least three police officers were wounded with arrows. The press office said around 500 protesters tried to 'invade' one of the entrances to Congress, and that police responded with tear gas, stun grenades and pepper spray after coming under attack with arrows.
