CAIRO — Seif al-Islam Gadhafi, the son and one-time heir apparent of Libya's late dictator Moammar Gadhafi, was killed in the northern African country, Libyan officials said Tuesday.
The 53-year-old was killed in the town Zintan, 136 kilometers (85 miles) southwest of the capital, Tripoli, according to two Libyan security officials in western Libya. The officials spoke on condition of anonymity because they were not authorized to brief the media.
Khaled al-Zaidi, a lawyer for Seif al-Islam, confirmed his death on Facebook, without providing details.
Abdullah Othman Abdurrahim, who represented Gadhafi in the U.N.-brokered political dialogue which aimed to resolve Libya's long-running conflict, also announced his death on Facebook.
Abdurrahim, who leads his political team, didn't provide further details, but Libyan news outlet Fawasel Media cited him as saying that armed men killed Seif al-Islam in his home. The outlet reported that prosecutors were investigating the killing.
Seif al-Islam's political team later released a statement, saying that ''four masked men'' stormed his house and killed him in a ''cowardly and treacherous assassination.'' The statement said that he clashed with the assailants, who closed the CCTV cameras at the house ''in a desperate attempt to conceal traces of their heinous crimes.''
Born in June 1972 in Tripoli, Seif al-Islam was the second-born son of the longtime dictator. He studied for a Ph.D. at the London School of Economics and was seen as the reformist face of the Gadhafi regime.
Moammar Gadhafi was toppled in a NATO-backed popular uprising in 2011 after more than 40 years in power. He was killed in October 2011 amid the ensuing fighting that would turn into a civil war. The country has since plunged into chaos and divided between rival armed groups and militias.
