Of course,any natural gas lines to the building might have been impacted by the explosion.

Fire is getting under control they said. Hopefully they can find out soon. Remember the explosion in New York weeks ago. It turned out to be chemicals. So this could very well be gas or propane from a barbecue.

Even if it was a barbeque, or oxygen, or a natural gas line, it still could have been done by terrorists. With the WTC bombing they used airplane fuel. If you want to blow up an apartment building, use the natural gas fuel source available. Not that I think it was a terrorist act, but I don't think it will be easy to prove one way or the other.
