PUNTO FIJO, Venezuela — An intense fire at a Venezuelan refinery spread to a third fuel tank Monday, nearly three days after an explosion killed at least 41 people and injured more than 150.
Vice President Elias Jaua said in a message that a third tank had ignited at the Amuay refinery, which has been in flames since Saturday’s blast.
Government officials had previously said they had the blaze contained, and the spread to another fuel tank was a setback to their plans to quickly restart the refinery. Oil Minister Rafael Ramirez said that the fire was still under control.
‘‘There is no risk of a bigger event,’’ Ramirez said, without specifying how much longer it might burn.
Officials have said a gas leak led to the blast, but investigators have yet to determine the precise causes. Prosecutor General Luisa Ortega said at a news conference that 151 people were injured, 33 of whom remain in hospitals.
