A report documenting “widespread and systematic” sexual violence during Hamas’s October 7, 2023, massacre, as well as assaults experienced by hostages held in Gaza, is set to be released Tuesday in Jerusalem, the British Sunday Times reports.

The Dinah Report, partly funded by the British government and written by Israeli gender and legal experts, aims “to counter denial, misinformation and global silence” over the massacre, and seeks “to set the historical record straight: Hamas used sexual violence as a tactical weapon of war.”

The report compiles testimonies from 15 former hostages, a survivor of an attempted rape at the Supernova Music Festival, and to 17 people who witnessed or heard assaults, which took place across six locations, according to the Sunday Times.

“Clear patterns emerged in how the sexual violence was perpetrated,” the Sunday Times quotes the report as saying, “including victims found partially or fully naked with their hands tied, often to trees or poles; evidence of gang rapes followed by execution; and genital mutilation.”
