A warning has been issued to anyone travelling to France after violent protests erupted in the country.
The Foreign Office has updated its travel advice for France, warning people their holiday could be disrupted by the demonstrations. It said: "Since 27 June, protests have taken place in Paris and other locations across France.
"Some have turned violent. The protests may lead to disruptions to road travel or targeting of parked cars in areas where protests take place. You should monitor the media, avoid protests, check the latest advice with operators when travelling and follow the advice of the authorities."

The Foreign Office website adds: "If demonstrations do turn violent, a heavy police/gendarmerie presence is to be expected. Avoid demonstrations wherever possible and follow the advice of the local authorities."
French protesters erected barricades, lit fires and shot fireworks at police in the streets of some French cities early on Friday morning as tensions mounted over the deadly police shooting of a 17-year-old that has shocked the nation. Armoured police vehicles rammed through the charred remains of cars that had been flipped and set ablaze in the northwestern Paris suburb of Nanterre, where a police officer shot the teenage delivery driver.
On the other side of Paris, protesters lit a fire at the city hall of the suburb of Clichy-Sous-Bois. In the Mediterranean port city of Marseille, police sought to disperse violent groups in the city centre, regional authorities said.
Tens of thousands of police officers have been deployed to quell the protests, which have gripped the country three nights in a row.
On Thursday, 100 people had been arrested by midnight, according to a national police spokesperson. The number was expected to rise as arrests underway were being tallied.
French President Emmanuel Macron held an emergency security meeting on Thursday about the violence. "These acts are totally unjustifiable," Mr Macron said at the beginning of the meeting, which aimed at securing hot spots and planning for the coming days "so full peace can return".
