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.
