Who Assassinated, Saeed Karimian, the GEM TV executive in Istanbul

The killing of Karimian, long a thorn in the side of Iran’s establishment, could signal a phase of risky new adventurism by the Tehran regime, or a further dimension of chaos within Turkey, a key US ally and NATO partner. Turkish police are rummaging through evidence, including closed-circuit television footage, in an attempt to unravel the mystery, which has shaken a city already unnerved by attacks from Islamist and Kurdish militants, political unrest over a failed 2016 coup, and a bitterly contested constitutional referendum last month.
