We were unaware of this development until a few hours ago when my wife tried to call our friends in Rostov. My wife is from Rostov-on-Don and I have spent considerable time there and even owned an apartment there some years ago.
Our friends live fairly close to the military air base, and while my wife was able to get through, internet was very bad and eventually the connection went dead. My wife called other friends that live near the city center and had better luck. Wagner group in the streets and regular military surrounding much of the city reinforced by Chechen fighters. Roads into and out of the city are blocked. According to our friends there is no petrol available, and the stores have been emptied of most food staples. Many folks are staying home and in basements. Now it seems most of the Wagner prisoner group are headed north to Moscow, and it seems Putin may have left and gone into hiding, but not real sure about the details.

Freaky to watch the videos of an area I know so well. Seems like all civilians are fine, but scared.
BUT, this "armed rebellion" is not against the war in Ukraine. It's against Putin and the military for not letting this group have all the resources they need to go on to win the war quickly.
Wanted to add that this Wagner group is dangerous. Primarily guys that were in prison. Bad and unpredictable hoodlums. Keep watching closely.
