The incident took place at the Olympic Stadium during Kiev???s 5-2 last-16 second-leg victory over the Merseyside team.
Dynamo advanced to the quarter-finals of the competition with a 6-4 aggregate victory and they will next take on Fiorentina.
But the triumph was followed by allegations which will be dealt with by UEFA’s control, ethics and disciplinary body on March 26.
UEFA said in a statement on its website that Dynamo face separate charges relating to racist behaviour, the setting off of fireworks and insufficient organisation – defined as allowing stairways to be blocked.
