"Honor killing" in Gaza - by her twin brother

From PCHR, referring almost certainly to the incident I mentioned last Sunday:

According to investigations conducted by PCHR, at approximately 23:30 on Saturday, 08 August 2011, the body of Kh. K. (32), from al-Zawaida village in the central Gaza City, was brought to the al-Aqsa Martyrs Hospital in Deir al-Balah .

The Palestinian Police went to the crime scene in al-Zawaida village, and found the victim's body with signs of strangulation. After that, the police arrested the victim's brother (H.K.), 32. The body of (KH.K) was transferred to the al-Aqsa Martyrs Hospital in Deir al-Balah then referred to the Forensic Medicine Department at Shifa Hospital in Gaza City, which reported that the victim was strangled to death.

According to investigations conducted by PCHR, the Attorney General is questioning the victim's brother for the victim's killing on the ground of the so-called “family honor.”

If both the brother and sister were 32, then they were (almost certainly) twins.
