Hi Mord,
I won't watch the BBC because it's a filthy Jew hating 'news' organization, but I have to say, I had the same thought. Israel immediately pointed the finger at Iran and with all of her enemies amongst the scum of scum, I'd like to hear some, even one, piece of evidence that nails Iran specifically. Israel needs to do a better job winning the media war and being good at making their case in the court of public opinion. If they know, A, B, C, D, then say it. They have so many facts, a good elucidation of their present understanding would have been a good media move in a country that is dealing with a never ending supply of home grown and imported Muslim fanatics
