Libyan National Security Adviser Ibrahim Abu Shanaf said on Sunday evening that no new demands should be opened in the Lockerbie case, after the settlement reached.

Lockerbie, a Scottish village, witnessed the explosion and crash of an American plane in 1988, killing all 259 people on board, in addition to 11 other residents of the village.

After a years-long political crisis between Libya and the United States, a Libyan citizen named Abd al-Basit al-Megrahi (died on May 20, 2012) was convicted of the incident on January 31, 2001, which prompted the regime of the late Libyan leader Muammar Gaddafi in 2008 to accept a settlement and pay more than Two billion dollars for the families of the victims to close the case.

Abu Shanaf's statements come the day after the Scottish authorities revealed, earlier on Sunday, that the Libyan Abu Ajila Muhammad Masoud Khair al-Muraimi, suspected of being behind the Lockerbie bombing, is being held by the United States.

Masoud is a former officer in the Libyan External Security Agency, who, according to US reports, was responsible for making the bomb used to blow up the plane, and he was the one who Libyan media reported in mid-November about being "kidnapped from his home in Tripoli."

Abu Shanaf said, "After the United States announced the capture of the citizen Abu Ajila al-Muraimi, we remind the American officials of their commitments and legislation issued in the settlement of the Lockerbie case."

He added, "The settlement agreement with Libya stipulates that, after paying money and compensation (to the families of the victims), no new claims may be opened for any acts committed by the two parties against the other before the date of the agreement."

And he added, "The United States committed itself, according to the agreement, to providing sovereign and diplomatic immunity to Libya, and that the families of the victims would not receive any compensation from the joint fund designated for the purpose, except after providing this immunity."

And he continued, "The US Congress also passed in August 2008, Law No. 110/30 submitted by the current (US) Representative and President, Joe Biden, which stipulates that the Libyan property and individuals concerned in the case shall be safe from seizure or any other judicial procedure."

And he went on to say, "Former US President George W. Bush issued in 2008 a presidential decree stipulating his country's commitment to completely ending any future claims and closing any cases opened by the families of the victims, whether before domestic or foreign courts."
