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.

Muhammadu Buhari was laid to rest in his hometown, Daura, in northern Nigeria. He leaves behind a mixed legacy, having been both a former military leader and a democratically elected president.

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.
