Indians block a road during a protest Tuesday against the government in Yurimaguas, northeastern Peru. The turmoil following the killing of police officers and Indians last Friday has saddled Peru’s President Alan Garcia with the worst crisis of his second presidency and set his government on a collision course with Peru’s seething native peoples and the global environmental community.

Tarapoto, Peru ? The Aguaruna Indians have a well-earned reputation as warriors. In pre-Columbian times they successfully resisted Inca subjugation. And during Peru’s 1995 border war with Ecuador, they served as guides for the army.

Those who know them weren’t surprised, then, at the fierce resistance — 23 officers were killed — when President Alan Garcia’s government sent heavily armed police to clear several thousand Aguaruna and their Wampi cousins from an Amazon highway blockade.

The ensuing turmoil has set Garcia’s government on a collision course with this Andean nation’s indigenous peoples.

London-based Survival International, which promotes tribal rights, called Friday’s melee “Peru’s Tiananmen Square,” comparing it with China’s bloody 1989 crackdown on pro-democracy protesters.

It was Peru’s worst political violence since the Shining Path guerrillas were quelled in the mid-1990s, and prompted Indian and labor groups to call a general strike for Thursday.

The strikers’ demands are the same as those of the protesting Indians: that Congress revoke laws to promote oil and natural gas extraction, logging and large-scale agriculture on traditional Indian lands. Garcia decreed the laws to comply with a new U.S.-Peru free trade agreement.

“We don’t get anything from this huge exploitation, which also poisons us. We’ve never seen any development and my community lives in poverty,” local Aguaruna leader Mateo Inti told The Associated Press in Bagua, the scene of Friday’s violence.

They also want Garcia and his Cabinet prosecuted for the bloodshed, which they say also killed 30 Indians. The government puts the civilian death toll at nine — outraging the Indian leaders who accuse police of burning and hiding more bodies.

“We’re not taking even one step back. We haven’t lost this fight,” protest leader Daysi Zapata said.

Peru’s government on Tuesday denied using excess force against the Indians.

“It has been irrefutably proven that the police were tortured and killed,” Ambassador Maria Zavala told the Organization of American States in Washington.

She said the government has tried to negotiate with the Indian groups but that they have grown more radical.

The government filed sedition charges against Alberto Pizango — Zapata’s boss in an organization representing 350,000 people from 56 Amazon nations.

Pizango took refuge Monday in the Nicaraguan Embassy, and the Central American nation announced Tuesday it was granting him asylum.

Also Monday, Garcia’s minister of women and social development resigned to protest the government’s handling of the crisis.

Carmen Vildoso said her resignation was “for political reasons, obviously,” but declined to elaborate. Cabinet chief Yehude Simon said she objected to government TV ads that show gruesome photos of slain police and claim an international conspiracy “wants to prevent Peruvians from benefiting from their oil.”
