LAGOS, March 13 (Xinhua) -- Nigerian President Muhammadu Buhari on Tuesday sacked Paul Boroh as Coordinator of the Presidential Amnesty Program for former Niger Delta militants.
In a statement made available to reporters in Abuja, the country's capital, Buhari also approved the appointment of Charles Dokubo as the new helmsman.
The Nigerian leader has directed the National Security Adviser (NSA) to carry out a full investigation into the activities of the Amnesty Program from 2015 to date.
The investigation should particularly cover the allegations of financial impropriety and other acts that are allegedly detrimental to the objectives of the Presidential Amnesty Program, the president added.
In June 2009, the Nigerian government offered amnesty to gunmen in the oil rich Niger Delta region, urging them to lay down their weapons by Oct. 4 in a bid to end unrest, which has cost Africa's top oil exporter billions of dollars in lost revenue.
Scores of Nigerian armed youth gave up their weapons and embraced amnesty offered by the Nigerian government in the most concerted effort yet to end years of fighting in the oil producing region.
The Niger Delta is an unstable area where inter-ethnic clashes are commonplace. Access to oil revenue is the trigger for the violence.
