Nigeria, May 19 -- Atiku Abubakar has threatened a lawsuit against a media aide to President Muhammadu Buhari, demanding a retraction and compensation over a social media post he considers defamatory.

Mr Abubakar's lawyers wrote to a letter to Lauretta Onochie on May 14, asking her to retract her post or face legal action.

The letter went out a week after Ms Onochie, a social media assistant at the State House, wrote on Twitter that the former vice president and opposition leader had been put on a terrorist watchlist in the United Arab Emirates.
