The striking refineries, which produce mainly gasoline and diesel for motorists, are the 339,000 barrels per day (bpd) Gonfreville, the 155,000 bpd La Mede and the 119,000 bpd Feyzin plants.

The action at the 230,000 bpd Donges plant was lifted over the weekend and preparations to restart production were underway, a union official said.
