A news outlet linked to the Islamic State jihadist group said Friday that its fighters were behind a bombing that killed nine people in Kurdish-dominated southeastern Turkey, according to US-based monitors.

"An insider source for Amaq Agency: Fighters from the Islamic State detonated an explosives-laden vehicle parked in front of a Turkish police headquarters in Diyarbakir in southeastern Turkey," the SITE Intelligence Group cited the IS-affiliated Amaq news agency as saying.
