Nigeria’s first lady has warned the “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 at powerful ruling party politicians, said the BBC’s Naziru Mikailu, in the capital Abuja.
They appear to be suspected of manoeuvring for presidency or deputy presidency while her husband is ill.
President Muhammadu Buhari has been in London 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, our BBC reporter says.
Mr Buhari has spent two periods of medical leave in the UK, the first in January, returning home in March. He hinted he had undergone a blood transfusion, but did not explain what had been wrong.
He returned to the UK in May, where he has been ever since. Mrs Buhari, who joined him earlier this month, said in June that he was “recuperating well”.
Mrs Buhari’s latest comments came in response to a post from Senator Shehu Sani, who warned that people were “scheming… so that they can be kings”.
