Gaza police have arrested family members over the deaths of two Palestinian teenage girls, one of them the victim of a suspected “honor” killing, an official said Monday.

The girl’s father had “beat her days before her death,” police spokesman Ayyub Abu Shaar said.

The Gaza-based Palestinian Center for Human Rights said a post-mortem showed signs of “torture” all over the girl’s body as well as signs of untreated gangrene from years of physical abuse.

The rights watchdog said the girl was 17.
