Journalists tour the ancient city of Palmyra in Syria, where many historic monuments have been badly damaged by Islamic State. Yiming Woo reports.
The Syrian government has invited journalists to see what's left of the ancient city of Palmyra - a place UNESCO describes as a "crossroads of cultures since the dawn of humanity". Last week, Syrian government forces, backed by Russian air support, drove Islamic State out of the city. Many ancient ruins suffered heavy damage, including the 2,000-year-old Temple of Bel. But others, like the Roman amphitheatre, were largely intact. Under the militant group's radical ideology, the preservation of pre-Islamic monuments is seen as a form of idol-worshipping. Syrian authorities say the city's not beyond repair, but the full extent of damage could take weeks to establish. Engineers also need to clear the ruins of mines. Syrian President Bashar al-Assad says Palmyra is a "treasure of cultural heritage" and has promised to restore it to its former glory.
