I have been trying to follow the evolution of the situation as best I could, and it is for once, I must admit, very hard to do from the US. That said, one thing is clear: The troops on both sides (President Kabila, and Jean Pierre Bemba) have withdrawn from downtown Kinshasa, following a UN-encouraged agreement, but Kofi Annan was still asking the two leaders to meet very soon, to put a formal end to all this.
In a secondary development, it seems as though the EUFOR troops that were stationned in Gabon, will now come to reinforce the ones already in Kinshasa, to bring back some semblent of order in the city, and the country. It seems as though they will now get a chance to prove they were not just there to protect the few, or to evacuate Western citizens.
In my search to find out what sparked all this, I found this press statement by the Congolese Chairman of the Joint Chiefs of staff, of the Armed Forces of the DRCongo (FARDC), Lt-Gen Kisempia Sumgilanga. Now the General is somewhat neutral, but he is also issued of the government troops that battled the rebels before the peace agreement of 2002. Keeping that in mind, in this statement, he established his version of the timeline of events, on August 20th, leading to this renewed crisis (Found here[fr] in La Conscience. I will provide a translation tomorrow, but the jist is that the FARDC were provoked, and they defend themselves.
