Cancer didn't kill Neruda: probe

International experts announced Friday that Chilean Nobel laureate Pablo Neruda did not die of cancer, but could not conclusively determine if he was assassinated by late dictator Augusto Pinochet's regime.

Neruda, a celebrated poet, politician, diplomat and bohemian, died in 1973 aged 69, just days after Pinochet, then the head of the Chilean army, overthrew Socialist president Salvador Allende in a bloody coup.

The writer, who was also a prominent member of the Chilean Communist party, had been preparing to flee into exile in Mexico to lead the resistance against Pinochet's regime.

He died in a Santiago clinic where he was being treated for prostate cancer.

The subsequent death of former president Eduardo Frei at the same clinic, where he had come for a routine operation, reinforced the thesis that Neruda was murdered.

"The (death) certificate does not reflect the real cause of death," Aurelio Luna said at a news conference on behalf of a panel of experts, referring to the official explanation that cancer killed the famed writer.

The group of 16 experts from Canada, Denmark, the US, Spain and Chile, 12 of whom worked in Santiago while the rest worked from abroad, could neither confirm nor rule out the hypothesis that Neruda was murdered.

The investigation began in 2011 after Manuel Araya, Neruda's former driver and personal assistant, claimed that he was given a mysterious injection in his chest just before he died.

Pinochet, who ruled Chile for 17 years, installed a regime that killed some 3,200 leftist activists and other suspected opponents.
