MEXICO CITY — Nicaraguan guerrilla fighter Humberto Ortega, a Sandinista defense minister who later in life became a critic of his older brother President Daniel Ortega, died Monday at 77, Nicaragua's army said.
The younger Ortega became the head of the Sandinista army and the country's defense minister after the overthrow of dictator Anastasio Somoza in 1979. Later in life, Humberto Ortega publicly criticized some actions of his brother's increasingly repressive administrations.
He had been ill and effectively under house arrest for some time. He died Monday at a military hospital, the Nicaraguan military posted on social media.
A cause of death was not provided, but a government statement said he had had a prolonged illness. It also praised his bravery in ''revolutionary military actions.''
Local media reported in May that police had surrounded Humberto Ortega's home, the same day online news outlet Infobae published a lengthy interview with him, in which he discussed his at times tense relationship with his brother.
He also characterized his brother's current administration as ''authoritarian, dictatorial'' in explaining that when the leader of such a government dies, it is very difficult for there to be continuity with the immediate group in power.
At the time, police said in a statement that the Health Ministry had visited 77-year-old Humberto Ortega, who suffered from heart problems, in his home and evaluated his health without ever saying why he was under police guard.
Venezuela President Nicolás Maduro expressed his condolences in a statement, praising Humberto Ortega as a freedom fighter.
