Oh, things are going so well in Iraq:

Authorities in northern Iraq have arrested four people in connection with the “honor killing” last month of a Kurdish teen — a startling, morbid pummeling caught on a mobile phone video camera and broadcast around the world.

The case portrays the tragedy and brutality of honor killings in the Muslim world. Honor killings take place when family members kill relatives, almost always female, because they feel the relatives’ actions have shamed the family.

In this case, Dua Khalil, a 17-year-old Kurdish girl whose religion is Yazidi, was dragged into a crowd in a headlock with police looking on and kicked, beaten and stoned to death last month. (Watch the attack, and what authorities are doing about it )

Authorities believe she was killed for being seen with a Sunni Muslim man. She had not married him or converted, but her attackers believed she had, a top official in Nineveh province said. The Yazidis, who observe an ancient Middle Eastern religion, look down on mixing with people of another faith.

This is Kurd Iraq, where things are going well. The police stood around and watched because she might have been associating with a non-Yazidi.
