Two firefighters, Wayne Brooks Jr. and Augusto Acabou, died following a cargo ship fire in Port Newark. Several other firefighters were injured, according to officials.

The fire started around 9:30 p.m. Wednesday in one of the cargo ships docked on the port.

Thousands of cars are on the ship and Newark fire chief Rufus Jackson says five or seven of those cars caught fire. The two firefighters made an attempt to extinguish the fire. He says because of the intense heat, the firefighters got pushed back out of the area where the initial fire was.
