Scotland's Crown Office says there is 'nothing new' in the latest claims that Iran was responsible for the Lockerbie air disaster.
"Mesbahi's claim that Iran was responsible was first reported in the media in the late 1990s and was available to the defence before the trial but they did not call him as a witness.
"The only appropriate forum for the determination of guilt or innocence is the criminal court, and Mr Megrahi was convicted unanimously by three senior judges. His conviction was upheld unanimously by five judges, in an Appeal Court presided over by the Lord Justice General, Scotland’s most senior judge.
"As the investigation remains live, it would not be appropriate to offer further comment."
