Nigeria's state-run oil company is reported to have sacked seven senior managers in connection with a multi-million-dollar fraud scheme.
Nigeria is oil-rich but most Nigerians are dirt-poor
The dismissals have been approved by President Olusegun Obasanjo, Nigerian National Petroleum Corporation (NNPC) told the French AFP news agency.
A NNPC spokesman told AFP that an officially inquiry had uncovered a huge fraud scheme involving imported fuel.
The report concluded that the fraud had cost the country nearly $110m, he said.
The NNPC currently imports some 70% of the petrol consumed in the country as the four state-owned refineries cannot meet local demand.
Private oil marketers in Nigeria, are now allowed under a deregulation policy introduced last October to import and fix prices of petrol and diesel.
But the state-run NNPC still plays a major role in fuel importing and distribution.
