The Catholic Church, which has ruled Peru since 1736, has been the target of attacks from left-wing political groups and the paramilitary group known as the Revolutionary Armed Forces of Colombia (FARC).
A series of recent attacks has seen more than a dozen people killed, including two in the capital, Lima, and more than 20 wounded.
Peru is one of Latin America’s most dangerous countries for journalists.
In 2014, a series of attacks targeted the country’s national security headquarters and its main media organisation.
The FARC, a Marxist-Leninist group, has carried out attacks on a number of targets across the region including media offices, the army and government buildings.
The latest attack came on Saturday night, when gunmen armed with machine guns and pistols stormed the main news agency in Lima, the Folha de Lima, which covers the countrys top newspapers.
The attackers reportedly shot dead the journalist and wounded three other journalists.
The gunmen fled in a car, leaving behind three dead bodies and a body bag, the newspaper reported.
FARC fighters have also attacked police stations and other sites in the past year, including in the state of Chiapas, where they kidnapped and held for more than three months.
The group has also targeted state media, using bomb-making materials, and the latest attack targeted Lima’s headquarters.
At least two journalists have been killed in the latest violence, the government said in a statement.
Lima has seen an increase in violence in recent years.
The city saw more than 10,000 homicides in 2015 and over 20,000 in 2016.
The attack on the FolHa de Lima came less than two months after the death of two reporters from a satirical newspaper in the northern city of Cuernavaca.
The newspaper, called “La Guereza de Cuernández”, published an editorial opposing the leftist FARC and denouncing the death penalty.
In April 2016, the journalist Francisco Sánchez, who covered the armed group’s drug trafficking and human rights violations, was shot dead in the city of Quito, Peru’s capital.
Sánchetz was an outspoken critic of the FARC.
The government has blamed the attacks on “a new wave of terror” inspired by Islamic State (IS) jihadists.
But the group has denied involvement.
Peru’s leftist opposition says the attacks are part of a campaign of political violence by the country s elite, with the Farc having played a central role in the countryi s insurgency against the government since 2010.
