Yaroslav Kirichuk, 6, plays with a balloon on Tuesday, April 28, 2015 in Lviv, Ukraine. After his father joined forces with pro-Russian rebels in eastern Ukraine, his mother Olga left him and other members of her family with anti-Ukrainian views and took her son to Lviv, where they live with a friend.
