BETHLEHEM (Ma'an) -- A man has confessed to strangling his 23-year-old sister to death in Nuseirat refugee camp in the central Gaza Strip on Friday, police told a rights group.

The woman's body was brought to the Al-Aqsa Martyrs Hospital in the early hours of Friday morning, the Palestinian Center for Human Rights said in a statement.

Police told PCHR the woman's father and two brothers were arrested on suspicion of murder, and one of her brothers confessed to strangling her to protect "family honor."

According to a 2011 survey by the Palestinian Central Bureau of Statistics, some 73.1 percent of never-married women in Gaza have been exposed to violence by a family member in their lifetime.

Of these women, 92.4 percent were sexually abused and 71.2 percent were physically abused.

Figures are even higher in the West Bank, where 84.8 percent of women have been exposed to violence by a relative. Most of these women -- 93.8 percent -- were sexually abused, while 84.2 percent were physically abused.

This article was amended to correct that 73.1 percent, not 73.6 percent, of women in Gaza have been exposed to violence by a family member.
