Paris, France (CNN) -- Ten of France's 12 oil refineries were stopping production Friday, an oil industry spokesman said, as the country went through a fourth straight day of strikes over pension reforms.
Unions said workers at all 12 refineries were taking part in the strike.
Yves Le Goff, a spokesman for the French Oil Industry Association, said there is currently no rupture in the fuel supply, but that did not stop consumers from lining up at gas stations across the country to stock up on fuel, just in case.
The work stoppage at the refineries was having a direct effect on the two main Paris airports, Orly and Charles de Gaulle. Both are supplied by a pipeline that comes directly from refineries that were shut down Friday, according to Trapil, the company that owns the line.
While Orly said it has enough fuel to last for 17 days, French media reported that Charles de Gaulle has enough fuel to last at least through the weekend.
A spokesman for Paris Airports would not confirm how many days the Charles de Gaulle fuel would last if the pipelines continued to be blocked, but said there was no concern.
"We are not at all worried right now," the spokesman said.
The strike is over government pension reforms, which have passed the lower house of Parliament and are now awaiting approval by the Senate.
