BAMAKO, Rabi'I 20, 1436, January 11, 2015, SPA -- Mali's President Ibrahim Boubacar Keita has approved a new government, the third since he took power less than two years ago, ahead of fresh peace talks with separatists in the troubled north of the vast West African nation, Reuters reported. In his decree, issued late on Saturday, Keita appointed Tieman Hubert Coulibaly, who served in Keita's first government, as defence minister. It also named Mamadou Igor Diarra as economy and finance minister. There was no change at the key foreign affairs and mines ministries. The decree comes after Keita last Thursday named Modiba Keita, who is not a relation of the president, as Mali's new prime minister. --SPA 13:27 LOCAL TIME 10:27 GMT www.spa.gov.sa/w
