On Sunday a militant group calling itself The Islamic Army In Iraq gave the French government 48 hours to overturn the ban on headscarves. Al-Jazeera said today that the group had extended its deadline for another 24 hours. France has vowed not to give in to the demand. Foreign minister Michel Barnier travelled to Cairo as part of a diplomatic drive to secure the release of the hostages who disappeared near Najaf two weeks ago. Mr Barnier said his country respected all religions and human rights and noted that Muslim leaders in France had also called for the journalists' release.
