A fire at Iran's oldest and largest refinery in the southwest killed one person, state media reported Sunday.

A leaky pump in an under-repair unit at Abadan refinery caused the fire on Saturday, killing a worker, according to the state-owned IRAN newspaper. Firefighters put out the blaze in two hours and operations remained unaffected, the report said.

Iran's deputy parliament speaker, Ali Nikzad, confirmed Sunday that some workers were also injured, media outlets said.
