Khamis Gadhafi, youngest son of slain Libyan dictator Moammar Gadhafi, was reported dead Saturday, exactly a year after his father died. There were conflicting reports about whehter Khamis Gadhafi was captured alive but gravely wounded after a gunbattle in Bani Walid, a pro-Gadhafi stronghold where fighting has raged for three days. Al Arabiya news agency reported that sources told it Khamis Gadhafi was severely wounded and arrested but that he later died. However, Al Arabiya also said, Mohamed al-Magarief, the head of Libya's democratically elected General National Congress, told the agency the late dictator's son was killed during the clashes. A Libyan journalist told NBC News that Khamis Gadhafi was captured while fleeing in a convoy. His right leg had been amputated, but it was not clear if that was a result of recent fighting or a previous injury. Dr. Mustafa Abushagur, sacked as Libya's prime minister last week, tweeted Saturday that Khamis Gadhafi's body was taken to a Misrata hospital, the Russian Times reported. The Guardian of London reported that a statement by the Libyan national congress spokesman, Omar Hamdan, said the 28-year-old was killed "in battle" but gave no further details. Khamis Gadhafi has been reported killed several times, including in an August 2011 NATO airstrike. The seventh son of Col. Moammar Gadhafi, he was known as one of the most hardline of Gadhafi's sons. The reports came after heavy fighting between the pro-Gadhafi garrison in Bani Walid and militias allied to the Libyan government. Khamis' alleged killing prompted wild celebrations in Misrata, Libya's third city, where fireworks and car horns filled the night, the Russian Times reported. He was reviled there for atrocities allegedly perpetrated by the 32nd Brigade, a special unit he formed after studying in a Russian military academy, the Russian Times said.

On Saturday, Magarief said not all areas of Libya had been liberated, Al Jazeera news agency reported. "The campaign to liberate the country has not been fully completed," Magarief said on state television. "Bani Walid's misfortune is that it has become a sanctuary for a large number of outlaws and anti-revolutionaries and mercenaries," Magarief said.
