Orange flames lit up the night sky as firefighters worked to cut down the blaze, leaving the building smoldering hours later.

At least 11 bodies were sent straight to the morgue, Fire Chief Li Ching-hsiu told reporters at the scene. Another 14 people who showed no signs of life were among 55 taken to the hospital. Official confirmation of death in Taiwan can only be done at the hospital.
