As a slight revision to this comment-- there are two towns in Ukraine with the same name and only minor variance in transliteration and its not clear which one they're speaking about. However, its more or less irrelevant because its no where close to the front of where the convoy stopped-- which occurs somewhere between 20-40 miles to the south of the supposed ambush.

Look at where the convoy was at per intelligence sources and then look at a map where they say they ambushed them. The ambush supposedly takes place on the north-east of Kyiv just south of Chernihiv and the 40 mile convoy was on the other side of Kyiv to the north-west by Hostomel.

It couldn't possibly be a true story and like most Ukrainian propaganda it doesn't withstand even remedial scrutiny.
