heartbreaking and tragic and horrific. stand by, harold and peter. i want to bring in nbc s gabe gutierrez, who is four hours southwest of kyiv. how does zelenskyy s address add urgency to what is happening on the ground right now in ukraine? well, andrea, a lot of urgency. president zelenskyy calling out the united nations and his descriptions of the atrocities in bucha made all of the more powerful, because they were done, he says, by a permanent member of the u.n. security council. gabe, i have to interrupt you because we re about to see the video that didn t play earlier. and it s very graphic. please a caution, with children at home. these are the images provided by ukraine s government.
