WASHINGTON (NewsNation Now) — The United States on Monday unsealed criminal charges against another suspect in the 1988 bombing of Pan Am Flight 103 over Lockerbie, Scotland that killed 270 people, most of them Americans.

The suspect, Abu Agila Mohammad Mas’ud Kheir Al-Marimi, is a Libyan intelligence official charged with two criminal counts related to the bombing. One person was found guilty in Scotland of the Lockerbie bombing in 2001 and freed in 2009 on compassionate release grounds. 

The announcement of prosecution against an additional individual carries personal significance for Attorney General William Barr, who is leaving the position next week but held the same job when the Justice Department, nearly 30 years ago, revealed criminal charges in the U.S. against the two Libyans. Monday is the 32nd anniversary of the bombing.

“This investigation is by no means over. It continues unabated. We will not rest until all those responsible are brought to justice,” Barr said at a 1991 news conference announcing the charges. “We have no higher priority.”

The head of the Justice Department’s criminal division at the time was Robert Mueller, who went on to serve as FBI director and as special counsel in charge of the investigation into ties between Russia and the 2016 Trump campaign.

Libya refused to extradite the men to the U.S. but ultimately agreed to a deal to put them on trial in the Netherlands.

The New York-bound flight exploded over Lockerbie less than an hour after takeoff from London on Dec. 21, 1988. Among the Americans on board were 35 Syracuse University students flying home for Christmas after a semester abroad.Trump says Barr resigning, will leave before Christmas 

The attack, caused by a bomb packed into a suitcase, killed 259 people on the plane and 11 on the ground.

In 1992, the U.N. Security Council imposed arms sales and air travel sanctions against Libya to prod Col. Muammar Gadhafi, the country’s leader, into surrendering the two suspects. The sanctions were later lifted after Libya agreed to a $2.7 billion compensation deal with the victims’ families.

One man — former Libyan intelligence official Abdel Baset al-Megrahi — was convicted in the Netherlands of the bombing, and a second Libyan suspect was acquitted of all charges. Al-Megrahi was given a life sentence, but Scottish authorities released him on humanitarian grounds in 2009 when he was diagnosed with prostate cancer. He later died in Tripoli.
