A militant group has posted a video showing the killing of nine abducted Iraqi police and army officers after an ultimatum it gave to the government expired.
The footage posted on the Internet by the Islamic State in Iraq showed a militant shoot the victims in the head with a pistol as they kneeled in an open field.
The al-Qaeda-led group had demanded that the government surrender within 72 hours officers involved in the suspected rape of a Sunni Muslim woman, among other demands.
