LIMA, Peru — Marxist rebels have killed two journalists and their driver abducted near the southern border of Colombia and Ecuador, President Lenín Moreno of Ecuador said Friday.

The three — a reporter, Javier Ortega; a photographer, Paúl Rivas; and their driver, Efraín Segarra — were working for El Comercio, a large daily newspaper in the Ecuadorean capital, Quito. They were kidnapped on March 26 on the border of Colombia and Ecuador, according to the newspaper.

“We have information that confirms the deaths of our countrymen,” said Mr. Moreno at a news conference in Quito. “It’s been confirmed that these criminals, it appears, never wanted to return them safe and alive.”

The bloodshed highlights problems ahead for governments in both countries, which in 2016 celebrated the signing of peace accords between the Revolutionary Armed Forces of Colombia, known as the FARC, and the Colombian government.
