In Mali, Prime Minister Abdoulaye Idrissa Maiga and his government resigned today, the president's office said, without giving a reason. The president's office said in a statement in Bamako today that the president will soon name a new government.<br/>'<br/>Maiga is widely expected either to serve as President Ibrahim Boubacar Keita's campaign director for next year's presidential election or to run in Keita's place. <br/>'<br/>Keita's presidency has been dominated by security challenges posed by Islamist militants in northern and central Mali, who have regrouped since a French military intervention in 2013 to wage regular attacks on troops, U.N. peacekeepers and civilians. <br/>
