TEL AVIV, Israel (AP) — An Israeli report released Tuesday said that Hamas used sexual violence as a “tactical weapon of war” in its Oct. 7, 2023, attacks, building on other investigations by international and Israeli rights groups and the United Nations.

Thirteen women and two men who survived captivity by Hamas said they experienced or witnessed sexual violence while held hostage in Gaza, according to a new report by a group of Israeli researchers known as the Dinah Project.

In March, United Nations experts said in a report that Israel had used sexual violence as a war strategy in Gaza, allegations Israeli prime minister Binyamin Netanyahu rejected as biased and anti-Semitic. The authors of the Bar-Ilan University document presented the report to Israel’s first lady Michal Herzog on Tuesday.
