Discontent over living standards in French Guiana has led to a large-scale blockade on Monday.
The territory has regained control of its space station (more on that later) but anger there is not going away.
Despite being in South America, French Guiana remains part of France and has been paralysed by protests against a lack of investment from the mainland.
Demonstrators, led by a masked group known as the 500 Brothers, have been fighting for $2.5bn (£2bn) in aid.
France has made an offer of £1m, which has been rejected.
The 500 Brothers called for a total shutdown on Monday, including road blocks, after a police officer was injured in protests last week.
Where is French Guiana?
While Guyana and Suriname gained independence from their colonisers (the UK and the Netherlands respectively), French Guiana never has. It is classed as an overseas territory; its currency is the euro and its official language is French, although many also speak Creole.
It is bigger than Belgium, but has a population of about 250,000 people (compared with Belgium’s 11 million).
Its tough environment – including scorching heat and sharks – was made famous in the 1969 book Papillon, which later became a film staring Dustin Hoffman and Steve McQueen.
What are people upset about?
Protesters have a catalogue of issues they want France to urgently address, from education and health needs, to rising violent crime.
“The State does not respect its commitments, the State does not respect French Guiana,” Olivier Goudet, a spokesman for the 500 Brothers told France’s RFI network on Sunday. “We need to mobilise in order to raise awareness and remind the State of its responsibilities.”
How are rockets involved?
French Guiana is largely covered in Amazon rainforest, with its development centred on a handful of towns hugging the coastline.
One of these towns – Kourou – is home to the Guiana Space Station, which is used by the European Space Agency and the French government to launch satellites into space.
They are calling for action under the slogan Pou Lagwiyann Dekole, which is Creole for “Let Guiana take off”.
Last month, the hooded 500 Brothers group took over the space station and delayed a satellite launch.
They relinquished their occupation last week, but continue to protest.
