Up to 55 people were injured during an explosion at a Prague film and TV school building during classes, Monday. At least two people so far are unaccounted for and rescuers have begun searching for them and others in the rubble. A spokesman for the Czech capitol's police said the blast, that collapsed much of the building's first floor and shattered the windows of nearby buildings, was "most likely a gas explosion."
