TRIPOLI, March 25 (Xinhua) — Suspected members of the Islamic State (IS) on Monday killed a civilian and kidnapped three others in southern Libya, a security source said.

“Gunmen in three vehicles attacked the town of Ghadwa and raided a number of civilian houses. The reasons for the attack are still unknown,” a source of the security directorate of the southern city of Sabha told Xinhua.

Ghadwa, the largest southern Libyan city, is located 65 km southeast of Sabha.

Libya’s eastern-based army has been carrying out a military campaign against terrorism and crime in the south since mid-January.

The army recently carried out an operation and freed several hostages held by militants in southern Libya, killing or capturing several kidnappers.
