Passing of Venezuela's Opposition Figure in Custody Described as 'Despicable' by US Representatives.

The US government has condemned the Maduro regime over the death of a imprisoned opposition figure, calling it a "clear indication of the abhorrent character" of President Nicolás Maduro's rule.

The political prisoner died in his prison cell at the El Helicoide prison in Caracas, where he had been detained for in excess of twelve months, as reported by human rights organisations and dissident factions.

The officials in Venezuela reported that the former governor showed symptoms of a myocardial infarction and was rushed to a hospital, where he died on the weekend.

Intensifying Tensions Between US and Venezuela

This new intervention from the US is part of an growing diplomatic spat between the White House and President Maduro, who has claimed the US of pursuing his overthrow.

In recent months, the US has expanded its troop levels in the area and has carried out a series of fatal attacks on boats it claims have been used for trafficking narcotics.

US President Donald Trump has alleged Maduro directly of being the head of one of the country's drug cartels—an allegation the Venezuelan president categorically refutes—and has hinted at military action "on the ground".

"The detainee had been 'arbitrarily detained' in a 'center of abuse'," stated the American diplomatic office for the region.

Background of the Arrest

The opposition figure was taken into custody in that year after joining several dissidents to contest the results of that year's election for president.

Venezuela's pro-government national electoral body declared Maduro the winner, even though opposition tallies suggesting their nominee had won by a overwhelming majority.

The electoral process were largely criticized on the global scene as flawed and unfair, and triggered unrest throughout the nation.

The former governor, who led the coastal region, was indicted of "stoking division" and "terrorism" for challenging Maduro's declaration of success.

Reactions from Rights Groups and the Political Rivals

Local advocacy group Foro Penal has expressed alarm over deteriorating circumstances for political prisoners in the South American state.

"One more detained dissident has passed away in Venezuelan detention centers. He had been imprisoned for a year, in segregation," posted Alfredo Romero, the body's director, on a social media platform.

He added that the detainee had only been granted one visit from his child during the whole time of his incarceration. He also mentioned that over a dozen political prisoners have passed away in the country since 2014.

Opposition groups have also denounced the administration over the death of the former governor.

María Corina Machado, a prominent dissident figure who was awarded this year's Nobel Peace Prize but who is in seclusion to evade detention, said that Díaz's death was part of a pattern.

"Unfortunately, it contributes to an disturbing and painful series of deaths of jailed opponents held in the aftermath of the after the vote suppression," she posted.

The opposition alliance said that Díaz "passed away unfairly".

His own political party, Democratic Action (AD), also honored the ex-leader, stating he had been wrongly imprisoned without fair treatment and had remained in situations "that infringed upon his basic rights".

Broader International Tensions

Strains between the United States and Venezuela have become ever more tense over what Trump has labeled efforts to curb the flow of drugs and migrants into the US.

• US bombings on ships in the Caribbean and Pacific have claimed the lives of more than 80 persons.
• Trump has alleged Maduro of "releasing inmates from his jails and insane asylums" into the US.
• The US has designated two Venezuelan trafficking organizations as terrorist organisations.

Maduro has for his part alleged the US of using its drug enforcement efforts as an justification to overthrow his regime and gain control of Venezuela's huge petroleum resources.

The America has also stationed a large fleet—its biggest presence in the area in decades—along with thousands of military personnel.

In a related action, the Venezuelan army according to reports swore in thousands of troops in one go on Saturday, in answer to what military leaders described as US "intimidation".
