Authorities say coca growers who oppose President Evo Morales have freed six hostages held after a weekend clash that killed a solider and a police officer.

Felipe Caceres is vice minister of social defense and he said Monday that three other people remain missing. Caceres says that the six released are police officers and soldiers who belonged to a coca eradication brigade.

Officials reported earlier that 10 other members of the joint military-police team suffered gunshot wounds and 10 were injured by blows in Saturday's attack in a rural area of the remote municipality of Apolo, about 90 miles (55 kilometers) north of La Paz.

It was the first fatal attack on an eradication team since Morales was first elected nearly eight years ago.
