And honor killings are a tribal practice that fall under a social and cultural frame, not an Islamic one. It doesn't have any basis in Islam at all.
Some people in Pakistan or Afghanistan kill their daughters in the name of "honor," but it's a primitive way of thinking and it was just a way of eliminating female members in the community who are generally seen as an economic liability since they are unable to provide heavy labor and must be fed by the family. So, their parents get rid of them by killing them or by drowning them, but, again, it has nothing to do with Islam. On the contrary, Islam is strictly against such killings, as the Quran says.
"And kill not your children for fear of poverty. We provide for them and for you. Surely, the killing of them is a great sin." (17:31)
