A woman crying Allahu akbar, God is great in Arabic, has injured two people with a box cutter at a supermarket in southern France, French media said.
Europe 1 radio quoted the prosecutor of Toulon as saying that a customer in the store in La Seyne-sur-Mer was injured in the chest in the Sunday morning attack and taken to hospital.
A woman at the market's cash register was injured too, but less seriously.
The radio station reported that Toulon prosecutor Bernard Marchal said the attacker has been detained.
