France fuel protests: 'Yellow vests' pull out of PM meeting
Protesters from France's "gilet jaunes" (yellow vests) movement have pulled out of a meeting with PM Edouard Philippe scheduled for Tuesday.
Some members of the group said they had received death threats from hardline protesters warning them not to enter into negotiations with the government.
The PM is due to make a major statement possibly as early as Tuesday.
The yellow vests oppose a controversial fuel tax but now reflect more widespread anger at the government.
A spokeswoman for the movement, Jacline Mouraud, said: "The meeting today at Matignon [the prime minister's office] has been cancelled in the face of threats.
"There are calls to prevent us from going. If I were to get on a train, I would run the risk of being recognised."
Three people have died since the unrest began and the resulting violence and vandalism - notably when statues were smashed at the Arc de Triomphe last Saturday - have been widely condemned.

"Yellow-vests" are so called because they have taken to the streets wearing the high-visibility yellow clothing that is required to be carried in every vehicle by French law.
The movement has grown via social media and has supporters across the political spectrum.
President Emmanuel Macron has accused his political opponents of hijacking the movement in order to block his reform programme.
How has the government responded?
The French president held an urgent security meeting on Monday. Ministers said that while no options had been ruled out, imposing a state of emergency had not been discussed during the talks.
Mr Macron has also cancelled a planned trip to Serbia to concentrate on the crisis.
Culture Minister Franck Riester told reporters that Mr Philippe would announce "a strong conciliatory gesture in the coming days", without giving details.
AFP news agency reports that the prime minister will announce a moratorium on fuel tax.
Mr Philippe also spoke to leaders of the opposition on Monday. He is due to meet MPs from the ruling La Republique en Marche party later on Tuesday.
Far-right leader Marine Le Pen, who was at the meeting, warned that Mr Macron could become the first president to give the order to open fire on his own people in 50 years.
Finance Minister Bruno Le Maire met business representatives to assess the damage caused to businesses over the weekend.
Some retailers had seen sales drop by around 20-40% during the demonstrations, while some restaurants had lost 20-50% of their takings, he added.
Who are the protesters?
The "gilets jaunes" movement began as a protest against a rise in duties on diesel - which is widely used by French motorists and has long been less heavily taxed than other types of fuel.
Mr Macron says his motivation for the increase is environmental, but protesters call him out of touch - particularly with non-city dwellers who rely on their cars.
The movement later grew to reflect a range of grievances, including the marginalisation of rural areas, high living costs, and general anger at President Macron's economic policies.
The protests have no identifiable leadership and gained momentum via social media, encompassing a whole range of participants from the anarchist far left to the nationalist far right, and plenty of moderates in between.
Nearly 300,000 people took part in the first countrywide demonstration. There were more than 106,000 a week later and 136,000 people last Saturday.
Do the protests show any sign of stopping?
Protests continued into Monday. About 50 "yellow vests" blocked access to a major fuel depot in the port of Fos-sur-Mer, near Marseille, and petrol stations across the country have run out of fuel.
Students in about 100 secondary schools across the country held demonstrations against educational and exam reforms.
Also on Monday, French private ambulance drivers staged further demonstrations against a range of social security and healthcare reforms they say could affect their services.
One protester told the Reuters news agency: "[The reforms] will bludgeon us financially and destroy our companies. We're going to have to fire people, that's for sure."
It is unclear whether the groups of students and health workers have directly aligned themselves with the "yellow vests".
One member of the movement, a man in his 20s, is in a critical condition in hospital in Toulouse.
He was injured in a clash with police.
