Former National Security Adviser (NSA), Col. Sambo Dasuki (rtd) has appeared in court in Abuja, Monday, charged with fraud, money laundering and criminal breach of trust.
Sambo Dasuki who denies the allegations, insists the case is politically motivated.
He was arrested with some of his associates two weeks ago by the Economic and Financial Crimes Commission, (EFCC).
A government investigative panel indicted Dasuki for allegedly diverting $2bn meant to buy arms for the fight against Boko Haram Islamist militants.
He was accused of awarding phantom contracts to buy 12 helicopters, four fighter jets and ammunition.
Dasuki appeared in court together with a former finance director in his office, Shuaibu Salisu, and a former general manager of the state oil company, Aminu Babakusa.
They have all pleaded not guilty. The trial continues Tuesday.
