France will close its embassies and schools in around 20 countries on Friday because of fears of a hostile reaction to a magazine\'s publication of cartoons of the Prophet Mohammed (PBUH), the foreign ministry said on Wednesday. Foreign Minister Laurent Fabius earlier announced that he had ordered special security measures “in all the countries where this could pose a problem.” Fabius admitted that he was “concerned” by the potential for a backlash to satirical weekly Charlie Hebdo\'s printing of a series of cartoons featuring the Prophet Mohammed (PBUH), against a background of violent protests in the Muslim world over an anti-Islam film.
