Scottish police and the FBI have requested permission to question two men identified as suspecs in the Lockerbie bombing.
They believe the two individuals were accomplices of Abdelbaset al-Megrahi - the only person to have been convicted of the 1988 atrocity that killed 270 people.
Megrahi, who was released from jail by the Scottish Government in 2009 on compassionate grounds after being diagnosed with prostate cancer, died in 2012 while still protesting his innocence.
Scotland's Lord Advocate, Frank Mulholland QC ,recently met the US Attorney General, Loretta Lynch, in Washington to review progress made in the ongoing investigation.
They have now requested permission from the Libyan authorities for Scottish police and the FBI to interview the two named suspects in Tripoli.
A spokesperson for the Crown Office said: “The Lord Advocate and the US Attorney General have recently agreed that there is a proper basis in law in Scotland and the United States to entitle Scottish and US investigators to treat two Libyans as suspects in the continuing investigation into the bombing of flight Pan Am 103 over Lockerbie.
“The Lord Advocate has today, therefore, issued an International Letter of Request to the Libyan attorney general in Tripoli which identifies the two Libyans as suspects in the bombing of flight Pan Am 103.
“The Lord Advocate and the US Attorney General are seeking the assistance of the Libyan judicial authorities for Scottish police officers and the FBI to interview the two named suspects in Tripoli.
“The two individuals are suspected of involvement, along with Abdelbaset Ali Mohmed al-Megrahi, in the bombing of flight Pan Am 103 in December 1988 and the murder of 270 people.”
The plane exploded as it passed over Lockerbie, killing everyone on board, and 11 more people died when large sections of the aircraft hit the ground.
