As France deals with widespread rioting, the Foreign Office says that Britons traveling there may run into problems and should keep an eye on the news.

In new travel advice, the British government told people to stay away from the riots because their places and times were “unpredictable.”

They also said that trip insurance was “more important now than ever”

Cops shot a 17-year-old Algerian boy on Tuesday, which led to riots.

He was killed as he drove away from a police stop. His death has brought up questions about racism in the French police force and brought up old arguments about the state of French law enforcement.

The Foreign Office changed its warning about going to France on Friday. It said that car travel and local transport could be hard, and that some local governments could set up more curfews.

It said that Britons should check with operators for the most up-to-date travel information and listen to what local officials say.

“It is more important than ever to purchase adequate travel insurance,” the government stated. It has also provided online-accessible guidance regarding insurance for international travel.

The Foreign Office’s current advice is that people should not travel unless absolutely necessary. If they did, many travel insurance plans would be canceled.

On Friday night, more violence broke out, and more than 470 people were arrested. However, France’s interior minister said that there had been a “downturn” in violence.

President Emmanuel Macron said that thousands of extra police officers would be sent to stop the violence, but he didn’t declare a state of emergency.

Paris Aeroport, the corporation that operates Orly and Charles de Gaulle airports in Paris, reported that there were transport issues between the city and the airports beginning at 21:00 local time.

As of early Saturday morning, the Eurostar train between the United Kingdom and France was operating as scheduled.

The Foreign Office says that about 17 million British people visit France every year.

Clamart, a neighborhood of Paris that was the first place to put in place a curfew, said that people couldn’t be out after 11 pm and before 6 am from Thursday to Monday.
