Rubble searched after Marseille building collapse

A residential building in France's port city of Marseille collapsed in a loud explosion early on Sunday followed by a fire deep within the rubble that hindered rescue efforts. More than six hours after the collapse of the five-story building before 1 a.m., it was not known if anyone was killed.

More than 100 firefighters were trying to put out blazes under huge piles of rubble in a slow and delicate operation aimed at keeping firefighters safe and trying not to harm people potentially trapped and not.Officials said two neighboring buildings were partially brought down and one was in danger of collapsing, creating a double challenge. Residents were evacuated and six were hospitalized, officials said.
