An early morning fire at 417 Sullivan St. has caused the loss of five buildings in the Keystone Ave. and Sullivan St. block of downtown Miami. A firefighter suffered a minor injury early in the stages of fighting the fire. Most of the buildings are approx. 100 year old and very close to each other which allowed for the fire to spread. Officials urge the public to stay away from the area so crews can make sure the fire is fully extinguished and so the investigation is unimpeded.
