Fire crews responded to a school-bus fire that burst into flames in Midtown on Tuesday morning at Seventh Avenue and 35th street.

The driver indicated that he was having problems with the bus. As he was driving it to a repair depot, it burst out in flames. There were some reports of a small explosion.

The Department of Education said the bus had eight special-education students onboard before it broke down. They were transported to another bus before the flames erupted. Neither driver nor any of the school children were injured.

There was fire all over, all over the smoke, people were coughing, it was crazy, it was crazy, it was really crazy, said one witness, according to NY1.com.

There was a lot of explosions. I guess it must have reached the battery of the bus and it looked like white phosphorous, and the firefighters were right there, and it's amazing how those guys are never scared, said another witness, according to NY1.com. I mean everybody was just running for cover after the explosions started happening.

After the fire was extinguished, the upper half of the bus contained fire burns and smoke damage. The windows were also blown out. Officials are currently investigating the blaze.
