What the Evidence Shows
Multiple independent sources report on leaked classified Israeli military intelligence data from May 2025 showing a high civilian death toll in Gaza during the conflict. According to investigations by The Guardian and 972 Magazine, the Israeli Defense Forces (IDF) database suggests that out of approximately 53,000 deaths, only about 17% were militants or fighters, while the remaining 83% were civilians. This proportion is described as an extreme civilian casualty rate rarely matched in modern warfare.

While these sources agree on the high civilian death rate, it is important to note that these figures come from leaked and classified data not officially confirmed by the Israeli government publicly. There may be political motivations influencing how data is presented or interpreted. Additionally, definitions of 'fighter' versus 'civilian' can be contested in conflict zones.
In summary, based on multiple independent journalistic investigations relying on leaked Israeli military intelligence data, the claim that by May 2025 only about 17% of Gaza’s approximately 53,000 dead were fighters and 83% were civilians is supported by credible evidence. However, some uncertainty remains due to the nature of leaked data and potential definitional ambiguities.
