Nigerian President Muhammadu Buhari returned to the West African country

Nigerian President Muhammadu Buhari returned to the West African country on Friday after a near-two month medical leave, but sounded a note of caution that he may need further treatment in the near future. The 74-year-old leader left Nigeria on the 19th of January for what was originally planned as a short vacation, including medical checks. But Buhari extended his stay in the UK due to medical advice, prompting speculation in Nigeria that he was critically ill or even dead, rumors which were consistently denied by officials.
