Mauritania has handed over Libya’s former chief of intelligence, returning one the most wanted members of Moammar Gadhafi’s fallen regime back to Libya, a spokesman for Mauritania’s president confirmed to CNN Wednesday.

Along with being wanted by Libya, Abdullah al-Senussi is wanted by the International Criminal Court for alleged crimes against humanity.

Al-Senussi, the late Gadhafi’s brother-in-law, was arrested in March at Nouakchott airport in western Mauritania, the Libyan transitional government has said.

Rassoul el Khal, spokesman for Mauritania’s president, said al-Senussi came into the country under a false identity.

Mauritania conducted its own inquiry in the matter, el Khal said, and granted the request of the Libyan government to send him back.

“A Libyan delegation made of up two minsters — justice and finance — came and brought back al-Senussi in a plane,” el Khal said.

The former intelligence chief was also wanted by France, which sought his extradition from Mauritania after his arrest, French officials have said.

Al-Senussi is the subject of an international arrest warrant after his sentencing in absentia to life imprisonment for the September 19, 1989, terrorist attack on UTA flight 772, killing 170 people, including 54 French nationals. The French airliner exploded over Niger.
