Former President Olusegun Obasanjo on Monday in Maiduguri, Borno state, called on the federal government to carry out in-depth research and document the root cause of the Boko Haram insurgency, so that the country and other African nations could learn from the experience.

Obasanjo made this call when he paid a courtesy call on Governor Kashim Shettima at the Government House Maiduguri.

The former president, who was in the state on an official visit at the instance of the University of Maiduguri, said the research became necessary in that Nigeria and other nations would learn from the mistakes that led to Boko Haram insurgency.

The former President and elder statesman said he was impressed with the achievement of the Nigerian military in the ongoing counter-insurgency operations, adding that the military must be commended for reducing the hostilities of the Boko Haram insurgents to the barest level.

He, however, cautioned the federal and state governments on the need to slow down in its desire to quickly relocate the IDPs back to their recovered communities even as he emphasised that it would be dangerous to do so, given the fact that the communities might still be dotted by landmines and explosives that could further endanger the populace.
