Former Argentine President Carlos Saul Menem died on Sunday at the age of 90 following heart complications, local media reported.
The former president died at the Los Arcos hospital in the city of Buenos Aires, where he had recently been admitted.
Menem, a member of the Justicialist Party that was founded in 1946, served as president between July 8, 1989 and Dec 10, 1999. His first presidential term ran from 1989 to 1995 and he was re-elected for a second four-year term.
He also served as a national senator for the province of La Rioja from 2005 until his death.
The current President Alberto Fernandez said of Menem on Twitter: "With deep regret, I learned of the death of Carlos Saul Menem. Always elected in a democracy, he was governor of La Rioja, president of the nation, and a national senator."
