The explosion at Venezuela's Amuay refinery last weekend killed 42 people, wounded 132 others and left eight people missing, Attorney General Luisa Ortega Diaz said.

We have "42 dead victims, of whom 41 have been identified," whose bodies have been released to relatives, Ortega Diaz told Venezolana de Television, or VTV.

Prosecutors have received "reports of eight people missing" in the explosion and fire at the energy complex, the AG said.

"Of the 132 injured people, only 20 remain hospitalized because the rest had only slight injuries," Ortega Diaz said.

The Amuay refinery, one of the three in the Paraguana Refinery Complex, or CRP, was rocked by an explosion last Saturday that started a fire and damaged about 500 nearby buildings.

The blast started a fire that burned for four days and affected nine fuel tanks at the facility.

Eighteen National Guard members died in the accident at the complex, which has a base and housing for guardsmen, Vice President Elias Jaua said over the weekend.

The investigation being conducted by the Attorney General's Office, the CICPC criminal investigations agency, the Sebin police intelligence agency and Petroleos de Venezuela, or PDVSA, specialists will "take the time needed," Ortega Diaz said.

The attorney general refused to speculate about the cause of the blast, saying that to do so would be "irresponsible" on her part.

The investigation will be "impartial, objective and impeccable," and it will "determine the truth," the AG said. EFE
