SOUTH WHITEHALL, Pa. (AP) -- A fire that destroyed more than two dozen school buses has forced a Pennsylvania district to cancel classes.

The fast-moving blaze at a Parkland School District garage in South Whitehall, near Allentown, was reported around 3 a.m. Friday.

Due to a fire in the bus garage that caused the loss of 25 buses, Parkland School District will be closed Friday, February 23, 2018. There will be no non-public transportation. Offices will open on time. Posted by Parkland School District on Friday, February 23, 2018

People who live near the site reported hearing explosions around that time. Authorities say the cause of the fire remains under investigation.

No one was injured, lehighvalleylive.com reported:

Superintendent of Schools Richard Sniscak said the 16 buses in the garage are a total loss and the nine to 12 others parked to the east side of the garage were damaged but might be salvageable.

The district has a lot of partners in local districts who may be able to provide buses and Parkland "has good relationships" with its bus vendors, Sniscak said.

"We hope to be back in operation on Monday," he said.
