Khamis, son of slain Libyan leader Muammar Gaddafi, has died following clashes with government forces, Xinhua reported.
The Libyan national congress' spokesperson Omar Hamidan, said in a televised speech that Khamis died on Saturday of injuries he sustained during exchange of fire with government forces in Bani Walid town, about 170 km from capital city of Tripoli.
Bani Walid, a former Gaddafi stronghold, has witnessed days of clashes after being sieged by factions which demanded the handover of a number of people accused of kidnapping and torturing Omran Shaban, who reportedly captured Gaddafi during last year's conflict.
Meanwhile, Libyan prime minister's office said in a statement Saturday that spokesperson of the former Gaddafi government, Moussa Ibrahim, has been captured in Tarhouna town, 70 km from Tripoli, by forces belonging to the present government.
Saturday marked one year since Gaddafi's capture and death near his hometown Sirte.
Gaddafi's regime was overthrown last year by opposition forces with NATO assistance after a seven-month civil war. Having ruled the country for 42 years, Gaddafi was captured and killed by rebels Oct 20, 2011.
