They are making much more progress in the south than I thought they would. Fairly early on in the invasion they were pushing into the south and I didn't know what to think of it, it seems like it should be easy to defend considering they are coming from an isthmus but they were being pushed back so I thought that maybe the Ukrainians deliberately left it lightly defended because they did not want to get caught there, so they would hold the river instead. But the Russians have crossed the river as well. I don't know maybe that area in general is lightly defended and they are going to hold them back closer to the capital, or maybe they want them to cross the river and they are then going to launch a counter attack and smash them.
Also, they are fighting in Chernobyl now...
