By Aidan Lewis TUNIS (Reuters) - Libya has not faced the same risk to its antiquities as Syria and Iraq, though there is evidence Islamic Sate is involved in the smuggling of antiquities, Libyan and international experts said on Wednesday. The most famous classical sites have remained largely undamaged, though some illegally excavated artefacts are being smuggled out of the country and Islamist fighters have targeted mosques and Sufi shrines, the experts said on the sidelines of conference on how to protect Libya's cultural heritage. Libya is rich in ancient sites, including some of North Africa's finest Roman and Greek ruins as well as prehistoric rock art in the desert region of Fezzan.
