Spymasters stand in as mediators for Doha talks
Two shadowy figures who frequently meet each other - Ahmed Kogri and Mohammed bin Ahmed al-Misnad - are steering negotiations in Qatar between Chad's government and rebel groups.
A creditor of both N'Djamena and Brazzaville, the oil trading giant is facing two very different situations. In Chad, which is seeking debt relief under the terms of the G20's "common framework", Glencore will have to accept the terms negotiated by the country's sovereign creditors.
The guerilla force currently laying siege to the regime of Idriss Deby is being directed from Doha by his nephew, Timan Erdimi. The situation is acutely embarrassing for the Chadian president but also for Paris, which is allies with Qatar but is fighting alongside the Chadian army against the rebellion.
The cold war triggered between Qatar and Saudi Arabia a year ago has had a ripple effect across Africa, where each oil monarch wants to rally as many supporters to his side as possible. Without a network of power on the continent, Riyadh and Doha have both turned to former African presidential advisors known for their discretion.
