At least 20 of the 29 people killed in a shooting at a Baghdad apartment building were women, a police officer and hospital official said.
The police officer said: "When we walked up the stairs, we saw a couple of women's bodies and blood streaming down the stairs."
He added: "We entered a flat and found bodies everywhere, some lying on the sofa, some on the ground, and one woman who apparently had tried to hide in a cupboard in the kitchen shot to death there."
There was no way to immediately confirm who was responsible for the attack.
