A fire at a Shell refinery east of Edmonton is partly to blame for a shortage of diesel fuel in Alberta.

Flying J Inc., which operates more than 20 diesel outlets in Alberta, said six outlets have run out of diesel and several others list their supply as "critically low."


Flying J partners with Shell Canada, which had a sour gas leak spark a fire at its Scotford upgrader in Fort Saskatchewan 10 days ago.

Shell spokeswoman Denita Davis said the fire and the increasing demand for diesel at this time of year are contributing to the shortage.
