Irish people travelling in France are being urged to exercise caution and be aware of their surroundings.
The Department of Foreign Affairs has issued the advice.
It comes after continued rioting across France, sparked by the shooting dead of a teenager by police in Paris.
The grandmother of the teen shot dead by police has called for an end to the violence.
The interior ministry says 45 thousand police officers and thousands of firefighters have been mobilised to enforce order.
Overnight, a 24-year-old firefighter was killed while fighting a blaze in an underground car park where cars had been set alight.
