The BBC contacted the Israel Defense Forces (IDF) for comment in response to Friday’s report.

The UN agency said it verified the details of 8,119 people killed in Gaza from November 2023 to April 2024.

Its analysis found around 44% of verified victims were children and 26% women. The ages most represented among the dead were five to nine-year-olds.

About 80% of victims were killed in residential buildings or similar housing, the agency added.

The report said the data indicates “an apparent indifference to the death of civilians and the impact of the means and methods of warfare”.

Gaza’s Hamas-run health ministry, whose figures the UN sees as reliable, has reported a death toll of more than 43,300 people over the past 13 months. Many more bodies are believed to remain under the rubble of bombarded buildings.

The health ministry said it obtained full demographic data for a majority of those killed and reported that children account for one in three of that number.

UN Human Rights Chief Volker Türk said in a statement that “this unprecedented level of killing, and injury of civilians is a direct consequence of the failure to comply with fundamental principles of international humanitarian law”.

He cited the laws of distinction, which requires warring parties to distinguish between combatants and civilians, proportionality, which prohibits attacks where harm to civilians outweighs military advantage, and precautions in attacks.

Türk called for a “due reckoning with respect to the allegations of serious violations of international law”.

The IDF has previously told the BBC in response to criticism that it “will continue to act, as it always has done, according to international law”.
