French schools in Tunisia will close from Wednesday afternoon until Monday morning due to security concerns, after a French weekly published cartoons of the Prophet Mohammed, the embassy in Tunis said. \"It\'s a preventative measure. We have not received any direct threats,\" an embassy source told AFP, adding that the mission would stay closed on Friday, when Islamist demonstrations following weekly prayers are common. Earlier the French foreign ministry in Paris said France will close its embassies and schools in around 20 countries Friday because of fears of a hostile reaction to a magazine\'s publication of cartoons of the Prophet Mohammed.
