The US trial of Lockerbie bombing suspect Abu Agila Mohammad Masud Al Marimi has been delayed again.

In 1988, all 259 people on board a Pan Am flight died in a bomb attack and 11 people were killed on the ground in Lockerbie, southern Scotland, by falling debris on December 21, shortly after the plane took off from London bound for New York.

Jury selection for Mr Al Marimi's trial had been set to begin in April 2026, but that date has been vacated, according to a recently filed court decision seen by The National on Sunday.

A summary from a Washington district court hearing in October explains several reasons for the much-anticipated trial's continued delays.

"An attorney on the defence team – who has represented Mr Al Marimi since the inception of this case – recently became aware of a conflict that required him to withdraw from the case," the summary reads in part.

Lockerbie bombing suspect Abu Agila Mohammad Masud's trial had previously been expected to begin in April of 2026.

The sheer volume of evidence is also mentioned as being troublesome for the trial timeline.

"Existing discovery in this case has come in the form of 10 productions, totalling over 356 gigabytes of data and consisting of over 413,000 separate files," the court document continues.

It said that Mr Al Marimi is eager for the case to get under way but "understands the challenges that his current attorneys face."

Judge Dabney Friedrich's decision to delay the trial rooted in 37-year investigation, was made on Wednesday according to court filings.

The US government initially filed charges against Mr Al Marimi in 2020, but it took more than two years to extradite him from Libya. His health problems, lawyer changes and logistical problems have caused the trial planning to move at a snail's pace.

In 2023, Mr Al Marimi pleaded not guilty in connection to one of the deadliest terrorist attacks in UK and US history.
