A Libyan security official says the former prosecutor general has been gunned down in his hometown eastern Libya.

The official says Abdel-Aziz al-Hassadi was assassinated in Darna late Saturday by unidentified gunmen.

The official didn't provide further details. He spoke on condition of anonymity because he was not authorized to brief the media.

Al-Hassadi resigned from his post in March citing health reasons. He is the latest former official assassinated in the country since the downfall of longtime dictator Moammar Gadhafi in an eight-month uprising in 2011.

The eastern region, hub of extremist Islamic militias, has witnessed series of attacks, assassinations and bombings over the past months targeting officials, judges, activists and clerics.
