I have contacts in Belarus. They were completely offline for 3 days since Sunday. Only today (12-Aug-2020 08:00 UTC approx) it seems the situation got back to normal and I've heard from them.
People are just terrified now and all they want is peace. They know that continuing protests is likely to result in a bloodbath and are understandably afraid of that.
I have a lot of friends from Belarus, and at least from IT sector, they are really eager to continue protests simply cause they are scarred what can happen if current government will stay
At this point, it's very difficult to know if the people who want protests to stop (even if they hate their government) are more numerous than the people who want the protests to continue and grow until the government can be replaced (with, from what I know in Belarus, is extremely unlikely - given that there's zero opposition prepared to take over the Government). But at least for now, things seem to be calming down instead of escalating.
Russia will take over or get involved. Do not kid yourself that they won't. Belarus has a direct border to Russia. They'll probably use protests to install a pro Kremlin government just like they did in Ukraine before Euromaidan sent him fleeing to Russia.
