Muammar Gaddafi’s regime was responsible for the murders of 270 people in the Lockerbie bombing, a new book claims.

Documents published in The Murderer Who Must Be Saved, by French investigative journalists Karl Laske and Vincent Nouzille and Libyan activist Samir Shegwara, are claimed to be the first written evidence that Libya’s intelligence service was behind the 1988 bombing.

The book reveals the existence of files allegedly seized from the archives of Abdullah Senussi, Libya’s former intelligence chief, who is understood to be in a jail in the north African country.

The BBC, which has seen the documents, says the papers appear to implicate Abu Agila Mas’id Kheir Al-Marimi, known as Masud, who is accused of building the bomb and is due to stand trial in the United States.

Masud pleaded not guilty to the charges after appearing in court in Washington in December 2022.

The documents also appear to implicate Abdelbaset Ali Mohmed al-Megrahi, who was convicted of playing a central role in the bombing, the BBC reported.
