RIYADH, Saudi Arabia, May 22 (UPI) -- At least 20 people were reported killed when a bomb detonated in an al-Qadeeh, Saudi Arabia mosque Friday.
Witnesses reported a blast, presumed to be a suicide bombing, at the crowded Imam Ali mosque in the small town in eastern Saudi Arabia. The Shiite mosque was filled with worshippers at Friday prayers, and the attack heightened worries about sectarian violence in the Sunni-majority kingdom.
