Nigeria’s first lady has warned that “hyenas and jackals” will be banished in a cryptic Facebook post apparently aimed at her husband’s officials.
Aisha Buhari’s comments seem to be directed towards powerful ruling party politicians, says the BBC’s Naziru Mikailu, in the capital Abuja.
The senior politicians appear to be suspected of manoeuvring for the presidency or deputy presidency while her husband is ill.
President Muhammadu Buhari has been in London since May receiving treatment.
The vice-president has been acting in his place while he is out of the country, but there is no suggestion he is part of any plot against Mr Buhari.
Mrs Buhari, who is also in London, says her 74 year old husband is recuperating well.
