The French government is attempting to reassure the public amid reports that fuel shortages have begun to affect the two main airports in Paris.
Strikes and blockades continue at petrol refineries in protest over pension reforms. But while the government says airports have all the fuel they need, it cannot say for sure what will happen if the blockades drag on.
There is the same concern on the roads, and while the government dismisses claims of likely petrol shortages, it is calling on the public not to “panic buy” at the pumps.
The prospect of fuel running out is a major headache for the government, as it tries to deal with an outbreak of violent demonstrations.
At least a million people took part in marches across the country on Saturday to voice their anger over plans to raise the retirement age.
Fringe extremist groups are being blamed for the violence.
