No it wasn't. It was a speculation by the LUL controllers as to what

Why do they need to speculate ? If an explosion happens in a LUL
tunnel, it is going to create on almighty bang. Everybody within range
will
know about it almost immediately. Don't they have cameras ? People
who report to them ? How come it took the LUL controlers 1h or so to
find-out that it had been an explosion ?

Because the symptoms were indicative of massive power failures and no one on
the spot was in a position to tell them otherwise for about twenty minutes.
A terrorist attack is not the first thing that comes to mind.
