France is preparing for more "yellow vest" anti-government protests, putting the nation on high alert as tens thousands of security forces were deployed to prevent the demonstrations from turning violent.
About 100 have been detained, many for possessing risky objects like fireworks or wearing clothing that could be used as protection in clashes with police.
Many economists and scientists, however, say higher fuel taxes are essential to saving the planet from worsening climate change.
"We can not take the risk when we know the threat", Culture Minister Franck Riester told RTL radio, adding that far-right and far-left agitators were planning to hijack rallies by "yellow vest" protesters in Paris.

"The troublemakers can only be effective when they disguise themselves as yellow vests". You can't get housing anymore.

Nationwide, 89,000 police officers were out in force in towns, cities and on numerous motorways which caused havoc on France's road network.
Macron agreed to abandon the fuel tax hike, but that has not defused the anger, embodied by the fluorescent safety vests French motorists are required to keep in their cars.
Paris police also reportedly asked dozens of shops and restaurants around the Champs Elysees and Bastille, which have been some of the main spots of the protests, to close.

Protesters using social media have billed the weekend as "Act IV" in a dramatic challenge to Mr Macron and his policies.
Some stores along the city's elegant Champs-Elysees Avenue had boarded up their windows as though bracing for a hurricane, but the storm struck anyway, this time at the height of the holiday shopping season. Police removed any materials from the streets that could be used as weapons, especially at construction sites in high-risk areas.
