Saudi women turned away from France for refusing to take off burkas However, Islamic rights campaigners have branded the ban "unconstitutional," saying that it persecutes moderate Muslims. Women face a fine of up to 150 euros or enforced citizenship training if caught breaking the ban, whilst men who force women to wear the niqab or burka face a fine of 30,000 euros. According to France's interior ministry, approximately 300 women were caught breaking the law during its first year in practice, however senior police officers have admitted that it is "unenforceable," and that "burka-chasing" is not high on police priority lists. Similar bans have since been passed in Belgium and Holland and whilst there are no immediate plans to introduce one in Britain, the idea has been suggested by a number of politicians, including Conservative backbenchers. Leaders of al-Qaeda's North African network have vowed to seek revenge if the law is ever enforced in France. They wrote on an Islamic extremist website: "We will seek dreadful revenge on France by all means at our disposal, for the honour of our daughters and sisters."
