Comfirmed by some pilots that are my friends that are in Arusha right now, and the pics are from one of them.
Arusha has a 1700mx30m runway with an elevation of 4600 feet and the biggest plane that operates there are ATR72 from Precision Air and most of the planes there are Caravans, But still with no explanation an ET B767 that was bound to JRO decide to land in Arusha, the runway category, fire services and all the infrastructures are not even close to be ready to accommodate a B767.
latest news reports that they were with the minimum fuel and they didn´t even have fuel to do Mombasa, but I think if this is the case this is so crazy!!!!! MBA is not even 150 NM from JRO. JRO was close due to a Caravan with a flat tyre on the runway.
