From the news sources i have in the UK (RT too), Kiev is under siege & blockage by Russian military. All roads in and out of that city are all shut and blocked. Heavy military hardware are all on the major exit roads out of Kiev as we speak. Russian military is embedded there now. All they have to do is sit and wait it out now. no food or medical supplies will get in to the city. also they will cut off the water supply. And they will cut off the electricity power supplies to the city. I refer you all to the Siege of Grozny for reading material. https://en.wikipedia.org/wiki/Battle_of_Grozny_(1994%E2%80%931995)
