The article above lists the gold and silver medalists at the All-Africa Games 10000 m as Ebrahim Gashu of Ethiopia and Bernard Muchiri of Kenya. According to the ARRS' competition rankings, these athletes are in fact Japan-based World Champion Ibrahim Jeilan Gashu (Team Honda) and Bitan Karoki Muchiri (Team S&B). Both runners train in Saitama prefecture. Ibrahim is cited as having won in 28:18.22, with Karoki just behind in 28:19.32. Awaiting confirmation of official results.
Update: Ibrahim's coach Kiyoshi Akimoto just confirmed to JRN that Ibrahim did in fact win.
Update: Unofficial results. These results list Karoki as 7th and Kenyan Kenneth Kipkemboi having taken silver, but that seems likely to be an accidental name reversal.
