Senegal's President Bassirou Diomaye Faye on Monday appointed Ahmadou Al Aminou Lo as the African nation's new prime minister.

Lo is replacing Ousmane Sonko, who was sacked on Friday, after months of simmering tensions between him and the president.

The sacking led to the resignation of all the members of the government and its dissolution.

Lo, who will now have to form a new government, previously served as head of the Senegal branch of the Central Bank ​of West African States. He also served as state minister to the president and secretary-general of Sonko's government.

Lo knows "the inner workings of the economy and finance," a presidential decree on announcing his appointment said.Senegal students feel betrayed, fear for futureTo view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video
