Worshippers in mosques across Guinea have been praying for the health of Nigerian President Muhammadu Buhari.
Mr Buhari has been in London for treatment for over two months, his second long visit for health reasons this year.
The Nigerian leader had been due to visit Guinea since March, but his trip has been postponed.
As a result, the Guinean President Alpha Conde asked his country’s mosques to dedicate a day of prayers to Mr Buhari’s recovery.
The illness Mr Buhari is suffering from has not been made public.
