PHOTOS: A massive fire burned in downtown St. Paul early Tuesday morning, apparently destroying a hotel under construction across from the Xcel Energy Center. The flames were more than 40 feet high at one point and visible on freeway traffic cameras nearby. Fire officials said shortly after 5 a.m. that a substantial part of the blaze had been knocked down. No injuries have been reported. Firefighters were climbing onto the roofs of nearby buildings, including the Catholic Charities homeless shelter across the street, to look for embers that may pose a fire threat nearby. Radio traffic among firefighters indicated at least part of the under-construction project had collapsed. Public works crews were also trying to boost water pressure to the area to aid firefighters.
