Four suspected jihadists were arrested Wednesday in the Paris region including one who was thought to be planning "violent acts", Interior Minister Bernard Cazeneuve said.

"We received information about one individual... that he might commit violent acts in France," Cazeneuve said on French television. "So this morning he was arrested along with three members of his entourage and checks are under way. I call on everyone to be extremely prudent regarding reports that are circulating about an imminent violent act."
