The military in Peru say that rebels from the left-wing Shining Path group have killed two soldiers in the jungle region in Ayacucho province.
Three other soldiers were injured. This is the second such attack in the area in recent weeks.
The group’s power and impact have declined since the arrest of its leader, Abimael Guzman, in 1992.
A military statement said the army would intensify the search for the guerrillas in the region.
In a similar attack last month, the authorities say the rebels ambushed and killed five soldiers.
The Shining Path was a powerful organisation in the 1980s and early 1990s.
It fought to remove what it described as Peru’s bourgeois democracy to replace it with a communist government, of Maoist inspiration.
The arrest of Abimael Guzman, in 1992, and a fierce campaign during the government of President Alberto Fujimori all but dismantled the organisation.
Drug Dealers:
Remnants of the Shining Path group are now said to operate in Peru’s Ene-Apurimac valley, in the southeast of the country, alongside drug traffickers.
Abimael Guzman is now serving a life sentence
The BBC Correspondent in Lima, Dan Collyns, says the Andean-Amazonian valley is a virtual drugs factory supplying Argentina, Brazil and Europe with high quality cocaine.
The area, known by its Spanish acronym as the VRAE, is also home to some of the Andean nation’s poorest people.
President-elect Ollanta Humala – a left-wing politician who as an army officer battled the Shining Path – will face key decisions when he takes office on 28 July.
Mr Humala’s election manifesto spoke of decriminalising coca farmers and even the low-level cocaine processors and smugglers.
Analysts like Ruben Vargas, a Peruvian security expert, says being too lenient with those involved in the drugs trade would be “naive”.
Gen Luis Howell, chief of the Joint Command of the Peruvian Armed Forces, says they are combating “not just terrorism but also drug trafficking”
