Venezuela's chief prosecutor has accused a US citizen recently arrested in the country of spying and planning to sabotage oil refineries and electrical services in order to stir unrest and kill innocent people.
The man, alleged to have CIA ties, had help from three Venezuelan conspirators, who were arrested last week near a pair of oil refineries on the northern coast, Venezuela's Chief Prosecutor Tarek William Saab said on state television.
The office gave the US suspect's name as Matthew John Heath.
The prosecutor showed pictures of equipment allegedly seized from the group, including a grenade launcher, plastic explosives, a satellite phone and a bag of US dollars.
Authorities said mobile phones taken from the men when they were arrested last week include images of a large bridge in Zulia state and dilapidated oil refineries in Falcon state.
"Everything here could qualify as a lethal weapon designed to cause harm and to promote assassinations, crimes against the people of Venezuela," said Saab, who also accused the man of planning to open a drug trafficking route through Venezuela.
President Nicolas Maduro announced on Friday that an unnamed suspected US spy had been captured, saying he was a marine and former CIA operative in Iraq.
US authorities have not commented on the case.
