Video showed hundreds of illegal immigrants storming a French airport and occupying an entire terminal Sunday, demanding to meet with the country’s prime minister.

Footage posted on Twitter shows roughly 500 migrants chanting in Terminal 2 of the Charles de Gaulle airport as about a dozen police officers in tactical gear look on.

“France does not belong to the French! Everyone has a right to be here!” one person can be heard yelling into a loudspeaker.

The protest was organized by the migrant support group La Chapelle Debout, which said their members call themselves “Black Vests.”

The group comes amid the country’s months-long “Yellow Vests movement” over tax reforms. French citizens are required to carry yellow vests in their vehicles for emergencies.

In an official statement, the group asked to meet with Prime Minister Edouard Philippe over the country’s asylum policy as well as the leaders of Air France. They demanded that the airline “stop any financial, material, logistical or political participation in deportations.”

Later Sunday, an Air France delegation met with the group, a member told local newspaper Le Parisien.

A migrant who took part in the protest warned it wouldn’t be the last.

“We have targeted Air France, and other actions will follow,” he told the paper.

The protest shut down the terminal, though airport operator Aeroports de Paris said no flights had been affected.
