Nigeria's government has rejected a media report alleging that it paid a "huge" ransom to Islamist militant group Boko Haram to secure the release of more than 200 pupils and staff abducted from a Catholic boarding school in November.
Information Minister Mohammed Idris described the allegation, made by the AFP news agency quoting intelligence sources, as "completely false and baseless" and a "disservice to the professionalism and integrity" of the security forces.
He also denied that two Boko Haram commanders were freed as part of the deal.
In a separate announcement, a presidential spokesman has said police chief Kayode Egbetokun, a close ally of President Bola Tinubu, has resigned.
The spokesman, Bayo Onanuga, said the resignation - a year ahead of the end of Egbetokun's term - was for "pressing family considerations".
