It was a fellow MJ that killed Abdirashid Ali Sharmarke, it was politically motivated, not tribally.Good question why MJ first act first. Maybe its the biggest treat on their way and take MJ out of the picture!. MJ in one point was part of Kacaan didn't believe one day the Kacaan was responsible of killed of President Sharmaake AUN. Dont forget we were the first group take weapon against Kacaan.
