Tourists with planned holidays to Paris - and other French cities - this weekend are being warned by the Foreign Office to exercise caution as protesters say they'll take to the streets again, calling the marches 'Act II'.  

The country has seen weeks of political unrest, with demonstrations over failing public services including education, the cost of living and food prices escalating to looting and riots in the French capital last weekend.

A British woman in Toulouse was also reported to have been injured by a projectile during protests last weekend, which 'tore half her calf off', local media said.

The UK Foreign Office this week updated its travel advisory, saying: 'There is an increased likelihood of demonstrations, political gatherings and marches taking place across France, sometimes at short notice.'

The Yellow Vest (Gilets Jaunes) movement, which has joined the protests started by students alongside trade unions and public sector workers has revealed plans to march across Paris on Saturday, starting at 2pm from Place de la Bastille. 

The Yellow Vests campaign, which sees protesters wearing high-visibility yellow safety vests, first began in 2018 and centred around public services declining and living costs soaring.

France's main student union, UNEF, has also urged protesters to rally again tomorrow despite French President Emmanuel Macron planning to meet with student representatives today. 

Mr Macron warned on Thursday that 'illegitimate' protests would be banned; previous attempts to curb the chaos, including curfews, have resulted in 2,700 arrests since last Saturday.

Action organised by trade unions and similar groups would be permitted but may be rerouted. 

'Those who want to cause disorder in city centres next Saturday will be prevented from doing so,' Mr Macron said during a visit to Qatar aimed at securing oil and diesel supplies in an effort to bring down prices, The Globe and Mail reports.

'There must be no wavering at the top of the state.' 

The Foreign Office advice suggests caution for those heading to the city, saying: 'Whilst most demonstrations are peaceful, you should remain aware of your surroundings. Stay away from areas with large crowds or a significant police presence, and follow the advice of police and local authorities.

'Demonstrations may disrupt local transport services and authorities may impose public safety measures, including partial and localised curfews in some areas. Monitor local media for the latest information about measures in your area.'

Some businesses and museums could close to avoid the unrest after last weekend saw demonstrations escalate to violence across France, with police struggling to contain protests in Paris, Lyon, Marseille and Limoges.

One incident even saw a British woman apparently injured by a projectile which tore half her calf off as she visited Toulouse on October 17, local media reported. 

Zephirin, a man who worked in one of the few restaurants in the city centre that was still open, said people were trapped between riot police and demonstrators.

Police were firing off tear gas and stun grenades at the rioters to keep them in check.

But one projectile seemed to have hit the British tourist, who was in the city with a companion.

Zephirin told Actu, a French news organisation: 'It pierced her flesh, her calf was torn off and a piece of plastic was lodged in her knee. She was bleeding heavily. It was very graphic and traumatic for the customers.'

Street medics who were treating injured protesters rushed to the woman and managed to stem the bleeding from her leg. Following this, emergency services took over and sent her to a nearby hospital.

Meanwhile, tourists on a river cruise in Paris got more than they bargained for as they watched the city be transformed into a 'battleground' by rioters last weekend.

Holidaymakers who booked a tour along the River Seine on October 17 had a front-row seat to the chaos choking the city amid violent protests.

The woman tour guide can be heard enthusiastically pointing out the Eiffel Tower as thick clouds of black smoke hung in the air above.

A large fire can be seen burning under a bridge as the boatload of tourists drew closer and loud sirens can be heard overhead.

A passenger who shared footage of the doomed tour to TikTok wrote: 'POV: You're on a Seine river boat cruise while Paris is burning.'
