A federal judge on Monday postponed a trial for a former Libyan intelligence official charged in the 1988 bombing of Pan Am Flight 103, which caused the aircraft to crash in Lockerbie, Scotland. 

The judge cited the discovery of new evidence that defense attorneys want to examine, CBS News reported. 

Abu Agila Mohammad Mas'ud Kheir Al-Marimi is charged with making the bomb that destroyed the aircraft and killed 270 people, most of whom were Americans. Jury selection was scheduled to begin Wednesday for his federal trial in Washington, D.C.

His lawyers say prosecutors disclosed new evidence to them on Saturday and said that their "constitutional and ethical obligations require the defense to investigate this development."

Neither the judge nor Al-Marimi's lawyers elaborated on the nature of the new evidence.
