Khaled al-Asaad
He looked after the ancient ruins of Palmyra for 40 years. Now ISIS has killed him.
ISIS militants beheaded a renowned antiquities scholar and hanged his body on a column in the ancient Syrian city of Palmyra. Khaled al-Asaad, 81, was apparently killed for refusing to reveal where valuable artifacts had been moved for safekeeping before ISIS seized the UNESCO World Heritage site in May.
