So now the explosion became massive and on the reactor building, while a half an hour ago CNN didn't know what and where exploded, and a professor from Tokyo on Japanese English media told people most of the fuel is safe inside the building, while commenting on the already can't be hided meltdown?

BBC still pretends in its latest blog update above, that it is not clear what exploded, even after showing the images. NHK already announced the main building roof and/or walls exploded, that means radiation will leak freely from now on. (link not available, from Japanese)
