The President of Nigeria says that he is alive. Rumors about his death have been circulating for months on social networks

For five months last year, Mr. Buhari, a candidate for re-election in Nigeria's presidential election in February, has disappeared from public life for treatment in London. With his return, the theory was born, fueled by some political opponents, which would have been replaced by a Sudanese impostor, a look-alike called Jubril.

Buhari's statements were then circulated by the Presidency in an e-mail release entitled "I am myself, President Buhari responds to the cloning request."
