BENGHAZI - Libyan fallen leader Muammar Gadhafi's youngest son Khamis is still alive, Libyan defense ministry source told Xinhua on Monday.

According to the high-ranking official who requested anonymity, Gadhafi's son Saif al-Islam told ruling National Transitional Council's (NTC) forces that his little brother Khamis is still alive.

The NTC forces have located Khamis' whereabouts in Terhouna, a city 90km southeast of Tripoli, and are expected to capture him in the coming hours, the defense ministry official said.

Gadhafi's second son Saif al-Islam, who had been wanted by the International Criminal Court on charges of crimes against humanity, was arrested in Sebha in southern Libya on Saturday. His confession has led to the capture of former intelligence chief Abdullah al-Senussi, another key figure in Gadhafi's regime.

Khamis' death was announced several times since Libya's conflict erupted. The NTC fighters claimed Khamis' death in the southeast of Tripoli on August 29, an allegation later "confirmed" by a pro-Gadhafi Syrian television station.
