France is gearing up for more mass protests this weekend as the political movement known as the “yellow vests” continues to draw popular support across the country. The protests began as a revolt against President Emmanuel Macron’s tax hikes on fossil fuels. Macron has since delayed the fuel tax, but protesters are now pressing more than 40 other demands—including a minimum pension, a reduction in the retirement age and tax reforms. During “yellow vest” protests last weekend, 400 people were arrested, and 260 were injured, as hundreds of thousands took to the streets. French officials said they might deploy armored vehicles in Paris for the first time in 50 years if protesters follow through on plans to erect barricades this weekend.
