Abdullah al-Senoussi extradited to Libya by Mauritania (VIDEO)

Abdullah al-Senoussi, Muammar Gaddafi's spy chief, has been extradited back to Libya, according to a statement released by the Mauritanian government, the Associated Press reported.

Al-Senoussi, who is accused of orchestrating some of the worst crimes under the Gaddafi regime, was put on a plane back to Tripoli, according to the statement.

Libya, the International Criminal Court and France had all asked to try the former intelligence chief who is accused of involvement in the 1988 Lockerbie bombing and a prison massacre in 1996, the AP noted.

The Libyan authorities confirmed that Al-Senoussi was handed over when his flight arrived in the country. He fled Libya last year after the uprising that toppled Gaddafi, and was arrested upon arrival in Mauritania, according to the BBC.

Al-Senoussi, Gaddafi's brother-in-law and right-hand man, was charged with entering Mauritania illegally and using forged documents, according to Agence France Presse. Mauritanian President Mohamed Ould Abdel Aziz said he would have to be tried for illegal entry, but Libya pushed for a handover.

The ICC issued an arrest warrant for Al-Senoussi on June 27, 2011, saying he was an "indirect perpetrator of crimes against humanity, of murder and persecution based on political grounds," in Benghazi, the AFP noted.

Paris also issued an international arrest warrant for Al-Senoussi, sentencing him in absentia to life in prison for his role in the bombing of a French airliner over Niger in 1989.

The BBC noted that his extradition to Libya is a blow for the ICC.
