Darfur NRF to reject AU mediation if Sudan accedes to African presidency

Sudan is to assume chair of AU by end of this month? Sudan Tribune publishes statement by NRF rebels threatening to reject AU mediation if Sudan accedes to African presidency. It seems to me what is going on in Darfur is a long drawn out attempted coup. Some days I think IDPs may as well just stand up and start walking, forget about Sudan, settle elsewhere and get on with life.
