Suspected Colombian leftist rebels have killed at least six police officers who were guarding work crews destroying coca plants in one of the country's national parks.
Authorities say suspected guerrillas from the Revolutionary Armed Forces of Colombia, or FARC, attacked the officers Wednesday in La Macarena National Park. The incident took place more than one week after a similar attack in the nature park left six police officers dead.
Last week's incident forced the government to send home some 600 of the more than 900 people working on the eradication project due to security concerns.
The work crews began ripping out coca plants in January as part of a government effort to eradicate illegal drug production from the park. Colombian President Alvaro Uribe ordered the project in December after FARC guerrillas killed 29 soldiers in the area.
