Russian military bloggers said Ukrainian forces had managed to breach through defensive lines in places south of Orikhiv, a town around 6 miles north of Roboytne.
It is a sign Kyiv has decided to commit thousands of well-trained troops, previously held back in anticipation for a breakthrough, to the assault.
Hopefully they have completely broken through the first line of defences in that area now. There are more defence lines before they get to Tokmak though. Tokmak itself is fortified as well.
Without air support, this was always going to be a very difficult counteroffensive. They are doing great work in what must be super challenging circumstances.
