Libya boasts five UNESCO World Heritage sites with well-preserved Greek, Punic, and Roman architecture. See http://www.unescoworldheritagesites.com/libya-unesco-world-heritage-sites.htm
What reports there are suggest they remain undisturbed for now. See

When Libya was an Italian colony, Mussolini lavished money on archaeology; excavations at Roman sites helped buttress his regime's claim to be the heir of ancient Rome. In reaction, Qaddafi largely ignored Libya's ancient past, labeling it as colonialist. Although there have been recent efforts to rehabilitate some sites for their potential as tourist destinations, Qaddafi and/or his cronies have also allegedly sold off statuary from ancient sites like Leptis Magna for personal profit. See http://phdiva.blogspot.com/2011/02/libyan-archaeology-scandals.html Like many despots, Qaddafi seems unable to distinguish between public property and his own.
Let's hope Libya's well preserved ancient ruins stay safe, and the Libyan people prevail in their death match with their eccentric tyrant, Col. Qaddafi, and his cronies.
