The fire was contained to the building’s front lobby. No one was hurt.

The mosque is about 75 miles from San Bernardino, where Syed Farook and his wife, Tashfeen Malik, killed 14 of his co-workers and injured 21 others on Dec. 2.

In a statement released Friday evening, California Rep. Raul Ruiz, whose district includes the area in which the mosque is located, called on authorities to investigate the fire as a possible hate crime.

“Our faith in humanity will not be intimidated,” he said. “And we stand together against any form (of) violence towards the innocent.” 

The FBI was assisting local law enforcement in determining the cause, agency spokeswoman Laura Eimiller said. The U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives also plans to help in the investigation.
