Guerrilla war in the French capital? An ambush of police officers by a platoon-size force of masked gunmen sure sounds like just that.

The CBC reports that four police officers responded to a call about vandalism at a bakery in the suburb of Grigny, an immigrant enclave with a large Muslim population.

When they arrived they were met by a group of 30-people wearing hoods, some of them armed. They opened fire, hitting three of the officers in the face with buckshot and wounding the fourth in the legs with a combined blast of shotgun pellets and nails.

This isn’t the first time Parisian police officers have been ambushed by armed gangs.
