A new Islamic State affiliate claimed responsibility Thursday for killing 15 people in a suicide bombing at a Saudi mosque used by security forces.
The Hijaz Province of the Islamic State said it carried out the attack. It made the claim in a Twitter statement hours after a suicide bomber detonated the explosive as worshippers prayed at the mosque in the southern city of Abha. The city is close to Saudi Arabia's southern border with war-torn Yemen.
The Hijaz Province statement said the group targeted a "monument of the apostate." Hijaz is a reference to the western part of Saudi Arabia, home to Islam's two holiest sites in Mecca and Medina. READ MORE OF THIS STORY
