One in every two Ukrainian children has been displaced since Russia began its invasion on Feb. 24, according to the UN Children's Fund.
"It's mind-boggling," UNICEF spokesperson James Elder told CNN. "Since the start of the war a month ago, out of every boy and girl in the country, one out of two now has had to flee their homes."
"It's a situation we've not seen before, not in living memory, and it's almost impossible to deal with," Elder said.
Elder said UNICEF is trying to get blankets, water purification tablets, generators, medical supplies and obstetric kits for mothers giving birth into the country.
"Unless the war stops, unless the indiscriminate attacks stop, we're going to see more children wrenched from their homes and the bombardments," he said, CNN reports
