At some point during the day, Ukrainian authorities warned the residents of Bucha not to get on buses that were "evacuating" out of the city, as they have not initiated any evacuation. Ukrainian authorities claimed that it was a ruse employed by the Russian forces to trail behind the fully loaded buses in order to gain entry into Kyiv, using the civilians as human shields.[16][17] This warning was also reported in Irpin on the same day.[18]
