Several French mosques were attacked following the killing of 12 people at the office of the French satirical newspaper Charlie Hebdo on Wednesday, according to reports.

Around 8pm local time on Wednesday, shots were fired in the direction of a Muslim prayer hall in Port-la-Nouvelle in southern France. Meanwhile Ouest-France reports that several percussion grenades were thrown into the courtyard of a mosque in Le Mans, west of Paris.

Local media also reported an explosion near a mosque in the town of Villefranche-sur-Saône in eastern France. The blast took place at 6am local time on Thursday at L’Imperial, a restaurant independently managed by people close to the mosque, where people attending the mosque often gather. There were no casualties reported. Le Progres quotes the town’s deputy mayor, Bernard Perrut, as saying he feared it was linked to Wednesday’s Charlie Hebdo attack.
