Up to 21,000 children is estimated to be missing in the chaos of the war in Gaza, many trapped beneath rubble, detained, buried in unmarked graves, or lost from their families, said Save the Children.

It is nearly impossible to collect and verify information under the current conditions in Gaza, but at least 17,000 children are believed to be unaccompanied and separated and approximately 4,000 children are likely missing under the rubble with an unknown number also in mass graves.

Others have been forcibly disappeared, including an unknown number detained and forcibly transferred out of Gaza, their whereabouts unknown to their families amidst reports of ill-treatment and torture.

The UN estimates that 10,000 people are believed buried under the rubble in Gaza, and also estimates that 40% of casualties in Gaza are children.

Save the Children estimates this would amount to approximately 4,000 children buried under the rubble in Gaza.
