A brief fire broke out during New York City’s Fourth of July fireworks celebration Saturday night after flames erupted on platforms used to launch pyrotechnics near the Brooklyn Bridge, sending thick smoke into the air before firefighters quickly brought the situation under control.

Dramatic videos captured smoke pouring from sections of the bridge area as fireworks continued exploding overhead during Macy’s annual Independence Day display over the East River. The flames appeared to spread across multiple launch platforms while the show was still underway, alarming many spectators gathered along the waterfront.

“At first I thought it was supposed to happen but then I was scared it would exploded. I thought the bridge was made of wood so I was scared,” said Nearing Khoula, 24, from France, who was watching the display from the Brooklyn waterfront.

“There were four at the same time. Some extra fireworks exploded due to the fire.”

Another witness, Mohamed Shaban, 31, of Egypt, described watching the flames intensify.

“It started as a small fire and got bigger. There was too much black smoke,” he said.

According to a reporter at the scene, the fires burned themselves out within about a minute.

A source familiar with the emergency response said the blaze was limited to temporary platforms that had been installed to launch the fireworks and did not involve the Brooklyn Bridge itself. The source added that the 143-year-old landmark remains safe and structurally sound.

The FDNY said firefighters extinguished the fire using two engine companies. No injuries were immediately reported.
