A fire broke out Wednesday in a building in downtown Tokyo in an area crowded with Halloween celebrants, paralyzing traffic, but no one was reported injured. The Tokyo Fire Department said the fire started in a commercial building on a backstreet in the Shibuya district of shops and restaurants which was packed with people in costumes for Halloween night.

The fire department said there were no reports of injuries. It said the cause of the fire was being investigated. NHK public television showed orange flames coming from a duct on top of the six-story building. A few firefighters were raised to the site on a ladder from one of the 16 fire engines sent to the area.
