A travel alert over more strikes in France has been issued by the Foreign Office.
The revised travel advice points to possible disruption on February 7 and 11.
This follows mass protests against a planned increase in the French pension age on January 19 which hit flights and rail travel.
The Foreign Commonwealth & Development Office said: “Several unions have called for cross-sector strike action and demonstrations on Tuesday 7 and Saturday 11 February.
“Industrial action may start the evening before a strike day and run until the morning after.
“Localised or sector specific strikes could also occur outside these dates.
“Industrial action may lead to disruption to services. Please check the latest advice with operators before travelling, avoid demonstrations and follow the advice of local authorities.”
