The BBC making their positon clear

It's all in the punctuation... From this piece of BBC reporting on the IAEA inspectors in Iran comes this line:

'In November, an IAEA report - based on what it called "credible" information - indicated that Iran had built in 2000 a large explosives containment vessel at Parchin to conduct hydrodynamic experiments.'

Am I alone in thinking that the purpose of those speech marks is less to indicate a quotation and more to illustrate cynicism at the quality of the IAEA's information?

The whole of that BBC article beautifully illustrates BBC bias and I may well return to it later.
