A building housing a mosque and school in the Twin Cities is a complete loss after an overnight fire, the facility manager said.

Crews were battling the fire when a WCCO photographer arrived at Baitul Hikmah Academy in Prior Lake around 2:30 a.m.

A congregation member told WCCO's Beret Leone that no one was inside at the time of the fire. No injuries have been reported, and the cause is unknown.

The facility's manager said the roof collapsed and the building is flooded. 

One neighbor said the commotion from the fire woke her up.

"We had no idea, no idea what was going on," neighbor Nancy Ufken said. "Then, when we started watching over by the mosque, we could start seeing smoke. And we did see some flames, but not until quite a bit later."

The private Muslim school is K-12 and serves about 200 students. Children from across the south metro attend it, neighbors said.

Baitul Hikmah has two other campuses. All three student bodies will be learning remotely on Monday.

WCCO is seeking more information from fire officials.
