Buhari, a former military general who campaigned on rooting out government corruption, has died at age 82, the presidential press office said in a statement on Sunday.

Nigeria's President Muhammadu Buhari, who has died age 82 in a London clinic, was a former military ruler and self-styled converted democrat who returned to power through elections but struggled to convince Nigerians he could deliver on the change he promised.

President Ruto also fondly recalled Buhari’s State Visit to Nairobi in January 2016, describing it as a milestone in strengthening bilateral ties between Kenya and Nigeria.
