Saif al-Islam Qaddafi, son and presumed successor of the late Libyan leader Muammar Qaddafi, is said to have been freed by the Abu Bakr al Siddiq Battalion which held him in Zintan for six years. The militia said it was acting on a request from the “interim government” based in eastern Libya, which had offered Qaddafi an amnesty. Saif al-Islam is under sentence of death in absentia by a court in Tripoli, which is ruled by the rival UN-backed Libyan government. Former reports of his release, which could further stoke Libyan chaos, have proved false.
