SPRINGFIELD, Mass. (AP) – Arson investigators were on the scene of a fast-moving fire that destroyed a city mosque on Wednesday.

Authorities had not been able to determine whether the fire that destroyed the Al-Baqi Islamic Center was suspicious because the remains of the brick building were not safe to enter, said Lt. Neil Hawley of the Springfield Fire Department.

A passer-by reported fire coming from the second floor of the mosque on Union Street at about 5 p.m., Hawley said. When firefighters arrived a few minutes later, fire was showing from the second and third floors.

“Fifteen minutes after that, it was through the roof,” Hawley said, explaining that a stiff wind made it impossible to fight the flames from inside the three-story brick building.
