A freight train derailed in Bensalem, Pennsylvania, sending at least ten rail cars off the tracks Tuesday afternoon.

Authorities said the incident happened near Street Road and Neshaminy Falls station, prompting an emergency response.

At least two of the cars were carrying hazardous materials, leading officials to deploy hazmat teams and order nearby residents to shelter in place.

No injuries were reported, but crews worked to assess the contents of the damaged cars and secure the area, Yahoo News has reported.

The cause of the derailment remains under investigation.
