In the days before being rousted by a French assault force, the leader of al-Qaida¹s branch in Africa had warned fellow Islamic fighters to go softly on the people in order to make their takeover of northern Mali last. The more than 10-page letter, which the AP found in a building the Islamists occupied for nearly a year, is signed by Droukdel, the senior commander appointed by Osama bin Laden to run al-Qaida's branch in Africa.
