Thanks to reader Desert Dweller for bring this to my attention.
The case was reported on a Saudi Arabian news site as an example of the "strife" the social networking site is causing in the Islamic nation.
It said the man shot his daugther after discovering she had been chatting online to a young man she had met on Facebook.
“Security sources assured Al-Arabiya.net that the father beat up his daughter and then shot her dead,” it said.
A leading Saudi preacher told Al-Arabiya.net that Facebook was a "door to lust" for women and called for it to be blocked to prevent social "strife".
Sheikh Ali al-Maliki said women were posting "revealing pictures" and "behaving badly" on the site, which has become popular with young Saudis.
Internet engineers said that young Saudis were using Facebook to flirt and make "web-cam calls".
Saudi Arabia imposes an austere form of Sunni Islam which prevents unrelated men and women from mixing, bans women from driving and demands that women wear a headscarf and cloak in public.
Dhimmi Watch points out that Muslim cleric al-Maliki is outraged over Facebook, not the honor killing.
