French emergency services have treated fourteen women for burns and itching on their hands and eyes after they touched a security code panel at a synagogue in Bonneuil-sur-Marne which had been coated with a chemical agent.
The incident took place after services had finished and soldiers charged with protecting the synagogue had finished their watch.
Twenty-five emergency medical staff had to be deployed and the victims have now returned home.
A police laboratory is now identifying the chemical used. Police are treating the incident as a criminal act.
