Arizona Mosque Fire Burns Two Firefighters, Cause Undetermined

GLENDALE, Ariz. (AP) -- The cause of a fire that collapsed the roof of a mosque and injured two firefighters remains undetermined, authorities said Wednesday.

Tuesday night's fire at the Al Sadiq Mosque is under investigation but it doesn't appear to be suspicious, said Mike Pena, a spokesman for the Glendale Police Department.

Alcohol, Tobacco, Firearms and Explosives officials were on the scene, which is standard procedure when a religious building is involved.

Two firefighters suffered minor burns, said Glendale Fire Department spokeswoman Julie Watters.
