LVIV, Ukraine—The Pryimenko family’s bags had been packed for five days on March 7, when Russia and Ukraine negotiated a green corridor for civilians to flee Sumy, Ukraine, which would open the next morning.
Vitaliy and Yekaterina Pryimenko had been waiting for a day to flee with their three sons: Kiril, 5; Yegor, 10; and Artem, 15. They had stayed put, having heard stories of civilian vehicles being shot at as they tried to escape Sumy, which is less than 25 miles from the Russian border.
