Who says Stuxnet is an Israeli project?

Remember that article in the Sunday Times that claimed that the Stuxnet computer worm had been developed by the US and Israel and that it was tested in Dimona? Jeffrey Carr doesn't buy it.And the proof? The journalists give none, because no one wants to go on the record. Fair enough, but with such a sensational claim I’d expect, at the very least, to read some additional supporting evidence.
