Ukrainian ambassador vows military will "liberate all Ukraine" amid counteroffensive

Washington — Oksana Markarova, Ukraine's ambassador to the United States, pledged Sunday that Ukraine's military will liberate all of the country from Russia as its armed forces continue its counteroffensive in the east to reclaim Russian-held territory.

"We always have to keep in mind that Russia still can do a lot of damage. But we don't have any other choice, we will advance," Markarova said in an interview on "Face the Nation." "As we said before, we will not surrender. And we will liberate all Ukraine, because this is what we have to do not only to restore our territorial integrity, but to save all of our people who are under occupation."
