Fears for ancient sites after earthquake destroys parts of Gaziantep Castle

Photographs show stones from walls of Roman-era building in Turkey have cascaded down its side

The partial destruction of a Roman-era castle in the Turkish city of Gaziantep has led to fears that two earthquakes that struck on Monday may have damaged other priceless monuments in Turkey and Syria, areas rich in cultural heritage.

Photographs and footage of Gaziantep Castle, considered one of the best-preserved citadels in Turkey, showed parts of its stone walls had cascaded down the side of the fort.
