Nigerian President Muhammadu Buhari is returning to his country, after spending more than 100 days in London for medical treatment. 

 

The 74-year-old left for the British capital on May 7th. His prolonged absence caused tensions back home with critics calling on him to either return home or resign. The health of Nigeria's leaders has been a sensitive issue since Nigerian president Umaru Yar'Adua died in 2010 after receiving treatment abroad. Many Nigerians hope Buhari can tackle urgent security issues in the country, like the country's Boko Haram insurgency.
