Libya's state news agency JANA said NATO forces stopped on Thursday a Libyan oil tanker, adding the forces are dealing with its crew.

The agency gave no further details, but it accused the alliance of committing "a piracy act."

Earlier, JANA said seven civilians were killed and 18 others were injured as NATO warplanes launched an air strike targeting Khelet al-Ferjan, a southwestern suburb in the capital Tripoli, late Wednesday.
