Any thoughts or rumours? Presumably it wasn't the obvious possibility of gas, or that would have been confirmed by now.
The police are saying there's no reason to think it was terrorist related, but perhaps it was crime-related (some family honour BS perhaps or commercial rivalry) ?
Or could it have been triggered by a short-circuited lithium battery in the basement, causing an explosion that in turn ignited a gas cylinder?
Definitely seems to have originated in the basement
