The beloved Spanish-language writer died at home in Mexico City around midday, sources told The Associated Press, confirming Mexican newspaper reports Thursday afternoon. The individuals spoke on condition of anonymity out of respect for the family's privacy.
Marquez won the Nobel Prize for Literature in 1982, with organizers hailing "his novels and short stories, in which the fantastic and the realistic are combined in a richly composed world of imagination, reflecting a continent's life and conflicts."
Considered one of the most popular Spanish-language writers of his generation, Marquez was born in the Colombian mountain town of Aracataca, which inspired the fictional village of Macondo immortalized in his generations-spanning family saga One Hundred Years of Solitude.
However, the media-shy writer endearingly dubbed "Gabo," had lived in Mexico City for more than 30 years.
A former film critic, journalist and foreign correspondent, Marquez eventually began writing fiction. He published the epic One Hundred Years of Solitude in 1967. Translated into more than 30 languages, it has sold more than 30 million copies around the globe.
His other works — including Autumn of the Patriarch, Love in the Time of Cholera, Chronicle of a Death Foretold, The General and His Labyrinth, Memories of My Melancholy Whores, Living to Tell the Tale and I Didn't Come Here to Make a Speech — spanned novels, novellas, short stories, a collection of speeches, essays, screenplays and a memoir.
Several of his works have also been adapted for other media, including the 2007 movie Love in the Time of Cholera and an opera based on Of Love and Other Demons.
In 2012, Marquez's younger brother, Jaime Garcia Marquez, said the celebrated author had been suffering dementia for some time and that the symptoms had accelerated since chemotherapy treatment for lymphatic cancer in Los Angeles in 1999.
However, Jaime Abello, director of the Gabriel Garcia Marquez New Journalism Foundation in Cartagena, disagreed. At the time, he said Marquez's condition was open to interpretation and that he was simply showing "the normal signs of his age."
Earlier this month, Marquez was hospitalized in Mexico City for dehydration and a lung and urinary infection, Mexico's health ministry said, adding at the time that he had responded well to treatment. He was released from hosptial last week.
Marquez's survivors include his wife, Mercedes Barcha, and sons, Rodrigo and Gonzalo.
