(Daily Mail)- A member of the Islamic State was found dead from an apparent smothering in western Mosul, putting the extremist organization in high alert, according to local reports.
The group put curfews in place in three residential areas in Tal Afar after the man was found dead, and ten people were arrested and sent to an unknown location as they searched for the alleged assassin, who's been dubbed the 'Mosul strangler'.

After the man stabbed the member of the Islamic State, the group shot the civilian, the witness said.

Soldier Asaad Hussein said: 'We leave them in the street like that so the dogs eat them. We also want the citizens to know there is a price for supporting terrorists.'
