CNN's Clarissa Ward spoke with a mother and her two young children as they took shelter in a subway station in Kharkiv, Ukraine.
She said they woke up around 5 a.m. local time when they heard explosions.
Her 9-year-old son said he was "so-so" when asked if he was scared.
She told Ward she thinks they will stay in the station tonight. They only have snacks and water.
She said she never thought they would be in this situation.
"We try to be brave because we have children and we don't want to show them that we are scared," she said.
