Nigerian President Muhammadu Buhari has arrived back home. The president is said to have touched down at the new Kaduna international airport early Friday, amid tight security. Buhari has been on medical leave in London for nearly two months. No official pictures of him or his meetings in London had been posted until Thursday. The presidency released photographs of him meeting the Archbishop of Canterbury Justin Welby. The 74 year old originally planned to stay in London for 10 days. He however, extended his stay twice, saying he needed further rest. His absence sparked concerns as rumours about his health continued to swirl. Vice President Yemi Osinbajo has been in charge during his absence.
