French Interior Minister Christophe Castaner has gone on Twitter to express his "disgust" as French yellow vest protesters set alight an anti-terror military car at a protest in Paris.

Such vehicles have been a common sight in Paris since the deadly attacks by extremists in 2015.

Paris demonstrators, who ended the 13th consecutive weekend of protest at the Eiffel Tower, set the vehicle ablaze in front of the famed monument.

Castaner said: "Every day the military ... protects our compatriots from the risk of terrorism. These attacks are intolerable."

Police said 31 demonstrators had been arrested Saturday as scuffles broke out between protesters and police. But the Interior Ministry said the protests are much smaller than last week's.
