An attack by extremist settlers on a Palestinian hamlet in the northern Jordan Valley over the weekend included a violent sexual assault, Haaretz reports, citing witness testimony.

“They pulled down the Palestinian man’s pants, poured water all over him, and brutally beat him into the dirt,” an American activist who was on site during the attack in Khirbet Humsa tells Haaretz.

“All he could do was curl into a fetal position and scream when they beat him with their clubs,” she recalls. “It was one of the worst things I’ve ever seen.”
