The Russian military convoy extended for more than 3.25 miles is now moving to Kyiv. 


According to satellite images, there are hundreds of military vehicles in the convoy, including tanks and self-propelled artillery.


The US says that it is observing the convoy which is likely to be used for a harsh attack against Kyiv. 


Ukrainian officials say that the capital city is encircled by the enemy which made it difficult to evacuate civilians.
