A Saudi woman has just been executed. She killed her husband by pouring acid on him while he was asleep. A horrible crime. She appealed, but I don't know whether the appeal was against the guilty verdict or against the death sentence. There is nothing online that I can find which explains the motive of the killing. It's simply been withheld, as though the crime happened in a vacuum. There must be a big back story, I'd guess about domestic violence, and it's being kept from the public.
