Peru's president has vowed to crack down on rebels who ambushed and killed eight soldiers in a remote region.
President Toledo wants to reduce the power of drug traffickers
Alejandro Toledo declared a two-month state of emergency in six central Peruvian provinces thought to be under the sway of drug traffickers.
The emergency measures allow troops to deploy in the area, raid homes and break up public meetings.
Remnants of Peru's leftist Shining Path guerrillas were blamed for Tuesday's attack in Huanuco province.
Announcing the emergency measures at a police barracks in Peru's capital, Lima, Mr Toledo blamed the violence on the escalating drugs trade in the coca-producing regions.
"They will pay," Mr Toledo said of the rebel groups.
"My government is prepared to provide everything that our police and our armed forces need professionally.
"The eight officers fell at the cowardly hands of terrorists who today are in the service of drug trafficking."
The ambush was the latest incident in an upsurge of violence linked to recent efforts to destroy coca crops.
Renegade Shining Path units are thought to be behind a series of attacks against security forces, despite the group's general defeat in the 1990s.
The Shining Path began a guerrilla campaign to topple the Peruvian state in the 1980s. The group is blamed for about half the 69,000 deaths occurred during two decades of civil conflict.
The group's leader, Abimael Guzman, was arrested in 1992 in a high-profile operation.
He is currently being retried for his role in the insurgency after a secret military conviction was quashed.
