BAMAKO, Rabi'I 13, 1436, January 04, 2015, SPA -- The mayor of a town in northern Mali died on Saturday from wounds sustained in an ambush that killed his son, one of a string of attacks highlighting persistent instability in the north of the country, Reuters reported. The death of Aroudeyni Ag Hamatou, mayor of Anderaboucane, came as a United Nations mission expressed concern over human rights abuses and violations of a shaky ceasefire between rebel and pro-government factions. Mali's government said Ag Hamatou died as he was being flown by the U.N. to Bamako for treatment. His son was killed and his driver injured when they were attacked by unknown gunmen, between Menaka and Anderaboucane in Gao region. "The government reiterates its pledge to punish those responsible for these crimes and fight against all forms of terrorism to restore peace and security to the whole of Mali," the government said in a statement. --SPA 13:52 LOCAL TIME 10:52 GMT www.spa.gov.sa/w
