On 19 May this year, the ancient city of Palmyra was about to fall. Jihadist fighters were advancing in pick-up trucks mounted with heavy machine-guns. They were from the group that calls itself Islamic State, also known as Da’esh and Isis.
Khalil Hariri, an archaeology expert who worked at the Syrian city’s museum, could hear the sounds of the fighting getting closer. Grunting and sweating, he and four friends kept on manhandling wooden crates out of the door of the museum and down to three trucks that were parked outside.
