Buhari - pictured here in 1977 with the then-King of Sweden Carl XVI Gustaf and Saudi Arabia's Sheikh Ahmed Zaki Yamani in 1977 - began his military career straight out of school. By the time this picture was taken, Buhari had risen to become a regional military commander.

Muhammadu Buhari, the former president of Nigeria who led the country as both a military ruler after a coup and later as the elected president, has died at the age of 82, his family said.

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.
