An explosion outside a Shiite mosque in Saudi Arabia on Friday killed at least four people, the Arab nation’s official Saudi Press Agency reports.
The incident comes one week after a suicide bomber detonated himself at another Shiite mosque in Saudi Arabia. That attack on Imam Ali mosque in the village of Qudayh — which happened as Shiite worshippers were performing prayers — killed at least 21 people and injured scores of others, Qatif Gov. Khalid bin Abdul Aziz Elsafaan said, according to the Saudi Press Agency.
ISIS later claimed responsibility for that carnage, signaling the Sunni extremist terrorist’s reach into yet another country after its successes in Syria, Iraq and Libya.
It was not immediately clear who was behind the more recent incident, though the fact that it occurred a Shiite mosque could be significant, given the longstanding divisions between Sunnis and Shiite Muslims.
