A horrific traffic accident between two New Jersey Transit commuter buses early Friday morning in the city of Newark killed at least one person and left as many as nearly two dozen passengers injured, some of them critically, according to multiple reports. The T-bone collision apparently happened after one bus crashed into the side of another, knocking it onto its other side. It was not immediately clear what caused the accident.

The person who died was one of the bus drivers, Newark Mayor Ras Baraka said, according to NBC New York. One of the bus drivers may have gone through a red light, Baraka added. That possibility was under investigation.

Emergency responders flocked to the scene of the accident, which took place just after 6 a.m. at the intersection of Raymond Boulevard and Broad Street, a major city thoroughfare. 

One driver told local news outlet PIX 11 that he thought the crash was a result of a bus driver trying to stick to his or her schedule.

"It's devastating," the unidentified motorist reportedly said. "People just need to respect the road. Take your time, be late. You are where you’re supposed to be at the time you’re there because that’s where God had you."

Photos from the scene show a grisly aftermath with victims being placed onto stretchers and gurneys as law enforcement and emergency officials and personnel surveyed the accident. Below are a few photos from the scene that have emerged on social media.

It was not immediately clear where the buses were coming from or going, but news of the crash comes during the same week that NJ Transit and the Port Authority of New York and New Jersey announced several changes to the bus line's gates at the Port Authority Bus Terminal in Times Square because of concerns over on-time performances, the Asbury Park Press reported. It was the second time in less than a year that such changes have been made.

This is a developing story.
