There are reports that Libyan rebels are claiming that Qadhafi is hiding Grad rockets among the spectacular Roman ruins at Leptis Magna, between Tripoli and Misurata. As a result, NATO is refusing to rule out air strikes against the ruins if they are concealing weaponry.
With so many human atrocities on record already in Libya, preservation of antiquities is naturally not anyone's priority, but Leptis Magna is a World Heritage Site and one of the best-preserved Roman cities anywhere. (North Africa as a whole, like the Middle East in general, often has far better preserved Roman ruins than Italy does.) I certainly hope it isn't damaged.
Trivia note: the name of Tripoli itself came from Latin Tripolis, the three cities, referring to Oea (Tripoli proper), Sabratha, and Leptis Magna.
