The rally appeared to have started peacefully.
The large sign above reads: "Students, Employees. Everyone in the Street. General Strike."
The rally was organized in opposition to Macron's economic reforms.
Symbolized here — but it later erupted.
Protesters smashed the windows at a McDonald's near the Austerlitz Metro station.
And reportedly threw one or more Molotov cocktails inside.
They also overturned and lit a car on fire near a Renault garage ...
... which appeared to have burned for awhile ...
... long enough for this man to pose in front of it with a beer.
Firefighters eventually put it out.
Riot police formed a barrier and fired tear gas at the protesters.
But they didn't seem to care, at least at first.
They formed their own barricade.
And threw colored-smoke bombs at the police.
Police eventually broke it up, arresting 200 people. Four people, including one officer, received minor injuries.
