The United Nations Security Council has expressed "concern" over the fate of the massive weapons stockpile built up in Libya under Colonel Muammar Gaddafi.
The council called on Libya and its neighbours to stamp out the proliferation of looted arms. It was worried they could fall into the hands of al-Qaeda and other militant groups.
Many weapons were destroyed in NATO operations, which ended at midnight October 31. However, officials said it was not clear how many were still in circulation.
The resolution, drafted by Russia and adopted unanimously, said that a huge stockpile of shoulder-fired missiles, which had been accumulated by Col Gaddafi, could still pose a threat to passenger aircraft.
The resolution also called on the new Libyan government to destroy chemical weapons in co-ordination with international authorities.
Overall, NATO aircraft flew more than 26,000 sorties, including nearly 10,000 strike missions. More than 1,000 tanks, vehicles and guns were destroyed, along with Col Gaddafi's command and control network.
