Hey, Temp, cool it. M23 are not (yet) the Khmer Rouge. Compared to the Army of the DRC the rebels are pretty disciplined. They are pulling back from Sake and Goma now, and will likely sit tight on the old front lines north of the city. The UN are still in Goma and the surrounding areas, and there's been no reports of conflict between M23 and the UN.
Good current reporting here:
M23 rebels in slow retreat from Goma - DR CONGO - FRANCE 24
There are dozens of "brave journalists" in Goma, and have been since before M23 got within 20 kms of the city. Most of us who are interested in the region have been keeping a close eye on M23 since early this summer when they first started moving south towards Goma.
I understand that in rural Vermont you might not get the latest news from Goma on the radio. In truth, we don't get much latest news from rural Vermont where I live.
But the amazing worldwide interweb is a good place to start, if you want to find out what's going on out here...
