A 64-kilometre line of vehicles, tanks and artillery has broken up, according to satellite imagery.
Satellite photos show a massive Russian convoy that had been mired outside the Ukrainian capital since last week appeared to have dispersed.
Imagery from US company Maxar Technologies shows the 64-kilometre line of vehicles, tanks and artillery has broken up and been redeployed, with armoured units seen in towns near the Antonov Airport north of the city.
Some of the vehicles had moved into forests, Maxar reported on Thursday.
The convoy had massed outside the city early last week but its advance appeared to have stalled amid reports of food and fuel shortages.
US officials said Ukrainian troops also targeted the convoy with anti-tank missiles.
