Four Libyan soldiers have been shot dead in separate incidents in the restive eastern city of Benghazi.
"Unidentified gunmen killed four soldiers and wounded another in Benghazi, while another was wounded in an assassination attempt," a security official told AFP news agency on Sunday.
A spokeswoman at the city's Al-Jala hospital, Fadia al-Barghathi, confirmed the deaths. The security official said the soldiers had been killed in separate attacks.
An officer died in a hail of bullets in the city centre district of Al-Hadaek. His son, who was with him in his car at the time, escaped unscathed.
The same source said three more soldiers were killed and one wounded in two attacks in the Assalem neighbourhood.
It was in Benghazi that the 2011 uprising which ended dictator Muammer Gaddafi's four-decade rule began.
The city has since been plagued by violence that has killed dozens of members of the security forces, judges and foreigners.
A suicide bombing targeting a security post near the city in December killed 13, and on May 2 five soldiers and a policeman died in clashes between jihadists and army special forces.
