Last evening on the communal balcony of my hotel (where the WiFi is strongest) about 50 yards from the square, I posted the first few photos of my trip from the airport. The pictures show the frustration evident by the people here and as I did that a conflict broke out in the square.
It turns out the "square" isn't actually much of a square so much as a patch of dirt, bordered by an 18-inch concrete curb, surrounded by a traffic circle (pictured right). Strings of large spiked barbed wire had been strung across street entrances, yesterday afternoon after police removed the barricades square dwellers had put up.
The drivers trying to get through expressed varying degrees of anger and frustration. I'm not sure that's what started the conflict seen in the pictures below, but it's possible. What my contact here assures me, is that whatever happened it wasn't revolutionary related, and things like this are not uncommon.
