Papers about the Lockerbie bombing which killed 270 people will stay secret, a judge has ruled.
They are thought to have been sent by King Hussein of Jordan to the UK Government after Pan Am Flight 103 was blown up over the town in 1988.
It is believed they allege a Jordanian agent made the bomb.
Lord Carloway, Scotland’s Lord Justice General, upheld an order by Foreign Secretary Dominic Raab that unsealing them would “harm national security”.
It comes after Scottish judges ordered protected documents held by the UK Government be released to the court as part of an appeal to clear the Lockerbie bomber.
The family of late Libyan intelligence officer Abdelbaset al-Megrahi want to review secret files as part of their case.
Foreign Secretary Dominic Raab has said producing the documents, which are covered by a public immunity certificate, would cause “harm to the United Kingdom Government’s international relations”.
He added any release would inflict “real harm to the national security of the United Kingdom”.
But appeal court judges said they would order two protectively marked documents (PMDs) to be produced to the court.
