New York City fire officials say they are trying to determine what caused a two-alarm fire at Macy\'s flagship store in midtown Manhattan. The fire in the basement of the block-long story was extinguished less than an hour after it began, USA Today reported Friday. The building was evacuated as a precaution but no injuries were reported, said Elina Kazan, Macy\'s vice president for media relations, in an e-mail. Fire officials reported the fire was under control by about 9:30 p.m. There was no immediate estimate of damage.
