The Nigerian president has ordered 20 former military chiefs and officers to be probed over alleged arms procurement fraud.
President Muhammadu Buhari's office noted that this was "on the recommendation of" a committee set up to examine procurement from 2007 to 2015. As part of the investigations, the activities of 20 companies will also be investigated.
Among them are the chiefs of defence and air staff under the last administration and a former security adviser to the government, Sambo Dasuki. He was charged in December over an alleged $68m fraud after accusations were leveled against him of awarding phantom contracts to buy helicopters, fighter jets and ammunition.
Mr. Dasuki has however denied the allegations and said they were politically motivated. A previous investigation found that phantom contracts worth $2bn had been awarded.
Others on the list include Alex Sabundu Badeh, a former chief of defence staff, and the former chief of air staff Adesola Nunayon Amosu who both served under former President Goodluck Jonathan.
These investigations are on founded on complaints made by Nigerian soldiers who reported that they did not have enough equipment to take on the insurgents in the fight against Islamist militant group Boko Haram,.
President Buhari who was largely elected on a promise to tackle corruption is reported to be delivering on the said promise.
