Flames break out on the Brooklyn Bridge during the Macy's Fourth of July fireworks over the East River and firefighters extinguish the blaze within a minute.The New York Fire Department deploys two fire engines, puts out the fire shortly before 10 p.m., and reports no injuries while the bridge remains closed to traffic for the celebration.Officials say small fires from fireworks are not uncommon, the show was scheduled earlier after severe weather threats forced cancellations and evacuations along the East Coast, and investigators will review damage and safety procedures.
