French police say they have issued their first penalty to a woman for covering her face with an Islamic veil.
The woman was stopped in a shopping centre in Paris on Monday evening - the same day that a law banning face coverings in public came into force.
Police said they gave the 27-year-old woman a ticket that requires her to pay a 150-euro (£133) fine or register for citizenship classes within a month.
France is the first country in Europe to publicly ban the Muslim face veil.
Under the law, any woman - French or foreign - walking on the street or in a park in France and wearing a face-concealing veil such as the niqab or burka can be stopped by police and given a fine.
People forcing women to wear the veil face a much larger fine and a prison sentence of up to two years.

Guidelines issued to police say they should not ask women to remove their veils in the street - if necessary they should escort them to a police station where they would be asked to uncover their faces for identification.
The French government says the face-covering veil undermines the basic standards required for living in a shared society and also relegates its wearers to an inferior status incompatible with French notions of equality.
The ban on face coverings - which does not explicitly mention Islamic veils, but exempts various other forms - has angered some Muslims and libertarians.
