Mali's government has resigned, and town planning minister Moussa Mara will become prime minister, according to a presidential spokesman who appeared on state television late Saturday.
Mara has been asked to form a new government.
The statement said President Ibrahim Boubacar Keita ended the duties of Prime Minister Oumar Tatam Ly after the government resigned. No reason was given for the government's decision.
President Keita was elected last August on a pledge to unite Mali and is seeking to rebuild the nation after a coup and a rebellion by Islamists.
The West African country spiraled into crisis after a military coup in the capital, Bamako, in March 2012. Several militant groups used the confusion of the coup to assert control in the country's north, where they planned to establish an Islamist state.
The violence prompted France to intervene in its former colony. A French-led military intervention pushed the militants from power but fighters have continued to stage small-scale attacks in the north.
