Nigeria's former President Muhammad Buhari was buried on Tuesday in the backyard of his home in northern Katsina state, as residents climbed trees to bid farewell to the 82-year-old.

Catholic leaders in Nigeria offer contrasting assessments of the role played by the immediate former President, Muhammadu Buhari, regarding the persecution of Christians in the country.

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.
