Peruvian hospital officials say three people have been killed in clashes between police and mostly indigenous protesters who tried to occupy an airport in southeastern Peru.
A doctor said the three people killed died from gunshot wounds Friday at Manco Capac airport in the city of Juliaca in Puno state. At least 12 people were injured.
More than 1,000 people were involved in the protest.
Many Aymara Indian farmers have been protesting since last month against a planned silver mine owned by a Canadian company, fearing it will pollute the water and leave few local benefits.
The farmers have also voiced opposition to a plan to dam several Andean rivers and build a large hydroelectric power plant.
