The American administration has condemned the Maduro regime over the death of a detained opposition figure, labeling it a "reminder of the abhorrent nature" of President Nicolás Maduro's rule.
The former governor died in his cell at the El Helicoide facility in Caracas, where he had been incarcerated for more than a year, according to advocacy organizations and political opponents.
The Caracas administration stated that the former governor displayed symptoms of a myocardial infarction and was rushed to a medical facility, where he died on the weekend.
This latest intervention from the US is part of an growing war of words between the American government and President Maduro, who has claimed Washington of attempting a change in government.
In the last several months, the United States has expanded its armed forces deployment in the region and has conducted a succession of lethal operations on boats it asserts have been used for trafficking drugs.
US President Donald Trump has accused Maduro directly of being the head of one of the area's narco-trafficking organizations—an allegation the Venezuelan president strongly rejects—and has threatened the use of force "on the ground".
"The detainee had been 'arbitrarily detained' in a 'torture centre'," said the US foreign policy division.
DĂaz was taken into custody in that year after joining numerous dissidents to challenge the results of that year's presidential election.
Venezuela's state-run election council declared Maduro the victor, even though figures from dissidents showing their candidate had triumphed by a landslide.
The elections were broadly rejected on the world stage as lacking in credibility, and triggered protests around the nation.
DĂaz, who was in charge of the coastal region, was accused of "incitement to hatred" and "extremism" for questioning Maduro's claim to victory.
Local rights organization Foro Penal has voiced worry over declining situations for detained dissidents in the Latin American nation.
"Yet another jailed opponent has lost his life in Venezuelan prisons. He had been incarcerated for a twelve months, in isolation," posted Alfredo Romero, the organisation's president, on a social media platform.
He noted that he had only been allowed one visit from his daughter during the whole time of his incarceration. He added that 17 political prisoners have died in the nation since 2014.
Dissident factions have also criticized the administration over the death of the former governor.
MarĂa Corina Machado, a leading dissident figure who won this period's Nobel Peace Prize but who is in seclusion to escape detention, stated that the governor's demise was part of a pattern.
"Tragically, it contributes to an disturbing and difficult series of demises of detained dissidents held in the wake of the after the vote suppression," she posted.
The coalition of rivals stated that DĂaz "died unjustly".
His own party, Democratic Action (AD), also paid tribute to the politician, stating he had been unjustly detained without fair treatment and had been kept in circumstances "which violated his human rights".
Strains between the United States and Venezuela have become increasingly strained over what Trump has labeled efforts to stem the movement of narcotics and immigrants into the US.
Maduro has conversely alleged the US of using its anti-narcotics campaign as an pretext to depose his socialist government and access Venezuela's enormous oil reserves.
The America has also positioned a sizable fleet—its most substantial presence in the region in decades—along with thousands of military personnel.
In a connected development, the Venezuelan army allegedly inducted more than 5,600 recruits in a single event on Saturday, in reaction to what army commanders called US "threats".
