Saif al-Islam, the wanted son of deceased Libyan dictator Col. Moammar Gadhafi, has been detained, along with several of his bodyguards, in the southern desert near Obari, Libya's interim justice minister and other officials confirmed Saturday.

After longtime speculation that he and his family's loyal supporters had fled the country, Zintan-based rebels announced Saturday, Saif al-Islam Gadhafi has been arrested along with three of his aides. The announcement was made by a Zintan field commander, Bashir Thaelba, at a press conference.

We have arrested Saif al-Islam Gadhafi in the Obari area, Justice Minister Mohammed al-Alagy told Reuters. He was in comparatively good health at the time of his apprehension.

Coming a month after the capture and gruesome death of his father Moammar Gadhafi and brother Mutassim Gadhafi, Saif al-Islam's arrest is a historical moment in the lives of Libyans.

We hope at this historical moment that the future of Libya will be bright, Thaelba said.

Celebrations began in the Libyan capital as fighters from the western mountain town of Zintan detained him near the town of Obari in the Sahara.

Saif, 39, had fled northern Libya after the capture of his father and was wanted by the International Criminal Court for charges relating to a horrific catalog of crimes against humanity.

Meanwhile, Interpol has issued a red notice to arrest Gadhafi's third son, Al-Saadi Gadhafi, 38, from the Niger territory where he was last seen.

The Interpol Red Notice against Assaadi [Al-Saadi] Gadhafi will significantly restrict his ability to travel and cross international borders, said Interpol Secretary General Ronald K. Noble.

Publicly called a mad dog by U.S President Ronald Reagan, the late Gadhafi and his sons are responsible for an appalling list of crimes committed during the past 42 years, including the support of terrorism.
