A massive fire broke out in a London high-rise apartment building early Wednesday (June 13th), with the fire commissioner saying that people had died, but she didn't know how many. At least 50 people had been hospitalized. The entire side of the 24-story Grenfell Tower was engulfed in flame as 200 firefighters battled the difficult fire. The cause of the fire wasn't immediately known, but residents said it appeared to start on a lower floor and spread upward quickly.
