Palmyra: Syrian forces advance against
IS held the ruins and the nearby city, known locally as Tadmur, for 10 months after seizing it for the first time in May 2015. It blew up temples, burial towers and the Arch of Triumph, believing shrines and statues to be idolatrous. They also destroyed the Temple of Bel the great sanctuary of the Palmyrene gods which had been one of the most important religious buildings of the 1st Century AD in the East.
