Sierra Leone’s ex-president Ernest Bai Koroma left the West African country by plane and flew to Nigeria on Friday, two Reuters reporters said, after a court allowed him to travel abroad on medical grounds despite treason charges. On Jan. 3, 70-year-old Koroma was charged with four offences for his alleged role in a failed military attempt to topple the government in November, but a high court on Wednesday ruled he could leave the country.
