And, as the war is ongoing – making it harder to gauge the full impact of the atrocities in Ukraine – agencies believe the real figures are much higher.
According to one mother, Oksana*, her eight-year-old daughter’s hair has started to turn grey from the stress.
“Look at my elder daughter, she is only eight and she has grey hair. I do not tell her, but when I braid her hair, I burst into tears, because she is a little child and they saw such things,” she told the photographers.
“It was very scary sitting in the basement, knowing that if – God forbid – the house was hit, you would be buried. You worried about yourself at that point, you’re scared for your children.”
Twelve-year-old Karina* also told the photographers: “There’s going to be something lacking. You know, the atmosphere of Ukrainian Christmas.”
Masha*, nine, said: “I would like my dad to come here or at least to talk to him over the phone. He said everything I draw may come true.
“So I drew for us to be together, for us to be at the seaside next summer…And when I was drawing him, I felt happy.”
She added that she wanted “peace” for Christmas.
Olha*, mother of seven, told Save The Children: “This year the mood isn’t festive. We just wish the war would be over, to live peacefully.
“We don’t want anything, no Christmas, no New Year. How can we celebrate? People are dying.”
She said that at night they “fear every rustle”.
Here are just seven images which provide a snapshot into the lives of Ukrainian children under attack from Russia right now.
The difficulties Ukrainian children are facing during this tumultuous period has not gone unnoticed in Kyiv.
The Ukrainian president Volodymyr Zelenskyy shared a video address on the first day of the new school year back in September. He said: “They stole part of your childhood, part of your youth…
“But you are free. You always will be. So be worthy of your will – and of our Ukraine.”
