Fire officials are trying to determine what sparked a series of explosions that burned vehicles at a western New York concrete company.
Authorities say the explosions were heard late Monday night at Kistner Concrete Products in the Genesee County town of Pembroke, 25 miles east of Buffalo.
When firefighters arrived, they found a truck on fire. The crews were able to get the blaze under control in about 30 minutes.
Officials say a tanker truck had caught fire and blew up. A second tanker parked nearby didn't explode.
The cause is being investigated.
No injuries were reported.
