French yellow vest protesters have clashed with riot police near the Arc de Triomphe on the 18th straight weekend of demonstrations against President Emmanuel Macron.

Protesters threw smoke bombs and other objects at officers, and started pounding on the windows of a police van. Riot police then retreated, as did a water cannon, with protesters kicking the side of the large truck.

Later, the water cannon unleashed bursts from a side street to try to push protesters back. A burning vehicle was seen nearby.

Police have announced 20 arrests already as protesters try to breathe new life into their movement against Macron and his policies.

After dwindling numbers in recent weekend protests, yellow vest groups organized dozens of rallies and marches Saturday in the capital and around.
