An armed attack by “terrorist groups” targeted Tazirbou wells field on Saturday morning and left an engineer and a security guard killed, the administration said on Facebook.

It added that the armed groups kidnapped two of the security personnel and stole all of the vehicles in the area.

“We have instructed the departure of all families of workers from the site for their safety and asked the concerned authorities and the municipality of Tazirbou to take the needed measures and provide necessary assistance.” The administration added.

According to local media outlets, the gunmen were about 20 and attacked the site using 5 cars and spent about 1.30 hours, saying it could be an attack by IS, whose militants are still active in southern Libya.

On Friday, an armed group abducted four foreign workers (three Filipino and one from South Korea) along with two Libyan nationals from Al-Hasawna area. The Libyans were later released.

The administration of the Man-made River warned of water cuts in western Libya, especially Tripoli, if attacks on its staffers continued, calling in a statement on the state authorities and elders of the southern region to interfere and release the foreign workers.

“The gunmen are entirely responsible for the safety of the abducted workers. They should release them immediately.” The administration added.
