(NBC NEWS) A police officer was fatally shot in a Paris suburb early Thursday, but the incident appeared unrelated to the execution of 12 people at a satirical magazine that ran cartoons of the Prophet Muhammad.
The shooting occurred in southwestern suburb of Montrouge at about 8 a.m. local time (2 a.m. ET). French Interior Minister Bernard Cazeneuve told reporters at the scene that two police officers had been shot and the suspect was "still at large."
