A fire halted operations on Wednesday at a coking plant of Petromonagas, a joint venture of the state oil companies of Venezuela and Russia, four sources told Reuters, adding that no one was injured.
A long plume of smoke was emitted from the plant in video images seen by Reuters. It was the second fire in less than a week at a facility linked to Petroleos de Venezuela SA (PDVSA).
The sources added that firefighters had brought under control Wednesday's blaze at a facility of the heavy oil upgrader in eastern Venezuela, while the rest of the facilities remained operational.
PDVSA did not immediately respond to a request for comment.
