Venezuela ordered American diplomats to leave the country within 72 hours on Tuesday after President Nicolás Maduro accused US counterpart Donald Trump of cyber “sabotage” that plunged the Opec nation into its worst blackout on record.

“The presence on Venezuelan soil of these officials represents a risk for the peace, unity and stability of the country,” the government said in a statement, after talks broke down over maintaining diplomatic links between the two countries.

Chief prosecutor Tarek Saab is also asking Venezuela’s pro-Maduro supreme court to open an investigation into opposition leader Juan Guaidó for participating in the “sabotage”, he said at a news conference on Tuesday.

Washington has taken the lead in recognising Mr Guaidó as Venezuela’s rightful president after the 35-year-old congress chief declared himself interim president in January, calling Mr Maduro’s 2018 re-election a fraud. Most countries in Europe and Latin America have recognised Mr Guaidó a president.

Mr Maduro, who retains control of the military and other state institutions as well as the backing of Russia and China, has denounced Mr Guaidó as a puppet of the United States.

With the power blackout in its sixth day, hospitals struggled to keep equipment running, food rotted in the tropical heat and exports from the country’s main oil terminal were shut down.

Julio Castro, of nongovernmental organisation Doctors for Health, said on Twitter on Monday night that 24 people had died in public hospitals since the start of the blackout. He has said the blackout likely aggravated existing medical conditions but did not directly attribute any deaths to the outages.

‘Sophisticated cyber attack’

Information minister Jorge Rodríguez said power had been restored in the “vast majority” of the country.

“We are on our way to consolidating the victory of the Venezuelan people over this attack,” said Mr Rodríguez. He added that the “electricity war continues”, a sign that authorities may be concerned about ongoing outages.

Power returned to many parts of the country on Tuesday, including some areas that had not had electricity since last Thursday, according to witnesses and social media. But power was still out in parts of the capital of Caracas and the western region near the border with Colombia.

Mr Maduro blamed Washington for organising what he said was a sophisticated cyber attack on Venezuela’s hydroelectric power operations. “Donald Trump is most responsible for the cyber attack on the Venezuelan electricity system,” Mr Maduro said in a broadcast from the Miraflores presidential palace on Monday night.

“This is a technology that only the government of the United States possesses.”

The US State Department had already announced that it would withdraw its remaining diplomatic staff from Venezuela this week.

Secretary of state Mike Pompeo said in an interview on Tuesday with radio show Texas Standard that decisions regarding Venezuela had been affected by the combination of a rapidly deteriorating situation and US diplomats being “in harm’s way”.

“We wanted to get them out of the country so that we could move forward in a way that provided that opportunity,” Mr Pompeo said.

Mr Maduro, elected in 2013 following the death of his political mentor Hugo Chávez, officially broke diplomatic relations with the United States on January 23rd when it recognised Mr Guaidó. Washington evacuated most of its diplomatic staff two days later.

The blackout was likely caused by a technical problem with transmission lines linking the Guri hydroelectric plant in southeastern Venezuela to the national power grid, experts told Reuters.

Economy in a tailspin

Venezuela’s electricity network has suffered from years of underinvestment and lack of maintenance. With the economy in a tailspin, spare parts are scarce while many skilled technical staff have fled the country amid an exodus of more than three million Venezuelans in three years.

The government suspended schools and business activities on Tuesday for two more days, after doing so on Friday and Monday. Mr Guaidó said he planned to lead national protests over the blackout in Caracas on Tuesday afternoon.

Amid signs of a growing crackdown on media, the National Press Workers’ Union said that prominent radio journalist Luis Carlos Díaz was arrested on Monday by intelligence agents, who raided his home in Caracas.

The Information Ministry did not immediately respond to a request for comment. Venezuelan authorities briefly detained American journalist Cody Weddle last week before ordering him to leave the country. – Reuters
