SANTIAGO, Chile -- Protesters have clashed with Chilean police during a demonstration against plans to build an airport on land claimed by the Mapuche indigenous group.
The Mapuche protesters hurled rocks and one fired a gun during the protest.
Police used tear gas against the protesters, who covered their faces as they blocked a highway in the southern region of Araucania.
Two police suffered minor injuries during Thursday's clashes.
Police say a group of men on Friday stopped two trucks in the nearby province of Arauco.
Police say the men ordered the drivers to get out and set fire to the trucks, which were carrying wood.
Small groups of Mapuche Indians have periodically attacked police and burned vehicles to demand land and autonomy.
