The youngest son of longtime Libyan dictator Muammar Gaddafi was captured and died on Saturday, according to unconfirmed reports by Libyan sources.

The sources told Al-Arabiya that Khamis Gaddafi, who was a military commander in charge of the Khamis Brigade of the Libyan Army, was severely wounded when he was arrested in the northwest city of Bani Walid.

Saturday marked the one-year anniversary of the elder Gaddafi’s brutal death, following his capture at the hands of citizens.

The Israeli attorney for the daughter of the former Libyan leader said Friday that those responsible for his murder a year ago should be brought to justice.
