Slog tipper Steve Geluso (via crackerjack reporter Krishanu Ray) sends these photos:It's a bit hard to make out, but there is a firefighter at the very top of that ladder extending over the blaze. There are unconfirmed reports on Twitter that what's burning in the picture is a metal factory belonging to the company Asko Metal and, importantly, that everyone is accounted for and no one has been injured.
