Reuters reports via Yahoo News the bomber who killed four others, and himself, in Ankara, Turkey, was affiliated with the Islamic State in next-door Syria. This is the second done by people from Daesh. They've been responsible for as many bombings as the Kurds this year.
Turkey has paid much more attention to Kurdish militants than to ISIS radicals, and perhaps that will have to change. If ISIS plans to make war on Turkey, the Turks can't very well continue to ignore them, even if that would be their preference.
