Fire-hit Venezuela plant reopens
Last Saturday's explosion at the Amuay refinery in the west of the country set oil tanks on fire for days.
The cause of the blast is unclear, but officials have pointed to a gas leak.
Two production units with a combined capacity of 160,000 barrels of oil per day are now back up and running, with a third due to restart soon, PDVSA said.
President Hugo Chavez, who has promised a $23m fund for clean-up operations, has said there is no evidence the explosion was the result of poor maintenance.
