“Afire Friday at a mosque appears to have been intentionally set, authorities say, and has prompted condemnations and alarm in this Riverside County community and beyond.
The fire at the Islamic Society of the Coachella Valley mosque is one of several incidents over the past week that officials are investigating as possible backlashes to the San Bernardino terrorist shootings.
Late Friday, authorities said they had detained someone but released no additional details.”
