Tensions erupted in Paris on Saturday at a protest led by the hard left against police violence, with a police car pelted with projectiles and a bank attacked, an AFP correspondent said.
The nationwide protest came just under three months after the point-blank killing by a policeman of a youth outside Paris at a traffic check sparked over a week of rioting in Paris and elsewhere.

They smashed the windows of a bank branch and threw objects at a police car that was stuck in traffic, an AFP reporter said.
Paris police said that the police car was attacked with a crowbar and only the intervention of an anti-riot police unit allowed the release of the vehicle.
Some 30,000 people were expected to protest across France, responding to a call by the radical left including the hard-left France Unbowed (LFI) party.
