A Libyan security official says an Italian engineer working in the eastern city of Tobruk is missing and that his car has been found abandoned in a street.

The official says 48-year-old Gianluca Salviato hasn't been seen since Saturday. He says there is no indication so far of a kidnapping. He spoke on condition of anonymity because he isn't authorized to talk to media.

In Rome, the Foreign Ministry confirmed an Italian citizen is missing in Libya and said it was in contact with the embassy in Tripoli.

Italian news agency ANSA says Salviato was inspecting work on a sewerage system that his employer, Ravellni, has been working on for two years.

It says colleagues are concerned about his health because his medication for diabetes was found inside the car.
