A fire ignited on New York City’s Brooklyn Bridge on Saturday night as the annual Macy’s Fourth of July fireworks show lit up the sky over the East River. No injuries were reported, according to local authorities, and the flames were put out within half an hour.

The Fire Department of New York (FDNY) dispatched two fire engines after receiving a report of a “rubbish fire on bridge” at around 9:40 p.m. local time, officials said. Crews extinguished the blaze shortly after 10 p.m. Fire was seen on at least three temporary platforms used to launch pyrotechnics, according to a departmental source cited in German media, and did not affect the bridge’s structure. The NYPD confirmed there were no medical emergencies and no evacuations were required.

The fireworks display, which commenced early to avoid approaching severe weather, was part of celebrations for the 250th anniversary of US independence. Spectators had been kept at a safe distance as a matter of routine, the FDNY said, because minor fires are not unexpected during such events. Elsewhere on the East Coast, storms forced the postponement or cancellation of festivities, including in Washington where the National Mall was briefly evacuated.

While the fire is widely attributed to the fireworks themselves, the precise cause remains under review. Preliminary assessments suggest the flames may have originated near the launch platforms rather than from a malfunction, according to US media reports. Authorities have not released a final determination, and the bridge, which was closed to traffic during the show, remained safe and intact.
