DUBAI, Jan 11 (Reuters) - Al Qaeda's North African wing has threatened to execute a French hostage if four al Qaeda prisoners being held in Mali are not released within 20 days.
Al Qaeda in the Islamic Maghreb (AQIM) issued its demand on an Islamist website often used by groups linked to al Qaeda and its supporters.
