Emergency crews were called to a freight train derailment in the Hazelwood community of Pittsburgh Thursday morning. At least 10 cars were reported overturned and lying off the tracks at the 4100 block of Second Avenue, the local CBS affiliate KDKA reported. The derailment happened around 10 a.m., according to emergency dispatchers. No injuries have been reported and a hazmat crew has not been called to the scene. It was unclear was type of freight the train was hauling, but most of the train cars appeared to be empty.

The Pittsburgh area derailment comes as federal and state officials were investigating Tuesday's deadly Amtrak crash near Philadelphia. The derailment killed at least seven people and injured dozens of others. Several presumed passengers also remained missing Thursday.
