Hatra, 68 miles southwest of ISIS-held city of Mosul, is 2,000 years old and is a UNESCO World Heritage site . ISIS have destroyed ancient relics such as this in Hatra, as they violates their fundamentalist interpretation of Islamic law . Last month, ISIS terrorists were pictured toppling crosses, smashing Christian relics with hammers and erecting the black flag of ISIS on churches in Nineveh, the ancient capital of the Assyrian empire. Pictured in civilian clothing, the ISIS thugs were seen overturning statues, destroying religious icons and replacing Christian crosses with the chilling ISIS banner. Elsewhere, ISIS went on a rampage in the Assyrian city of Nimrud in northern Iraq, destroying the 3,000 year-old winged statues placed at the gates of the Palace of Ashurnasirpal. The jihadists also bulldozed ruins in Hatra in March. ISIS have also set off bombs around Mosul Central Library, destroying as many as 10,000 priceless and irreplaceable books and manuscripts. UN Secretary-General Ban Ki-Moon called the Nimrud attack 'a war crime.' Hatra, 68 miles southwest of the ISIS-held city of Mosul, was a large fortified city during the Parthian Empire and capital of the first Arab kingdom. It is home to numerous temples and sculptures dedicated to gods including Apollo and Poseidon. The video comes in the wake of a major blow for ISIS, with Saddam Hussein's hometown of Tikrit falling into the hands of the Iraqi government. Tikrit is 80 miles north of Baghdad on the main highway to Mosul, Iraq's second-largest city. Meanwhile Isis has taken control of 90 per cent of a Palestinian refugee camp on the outskirts of Damascus - only a few kilometres from Bashar al-Assad's stronghold. A human rights monitoring group claimed that the terror organisation almost has full control of the camp which has a population of 18,000 civilians. The United Nations said it was very concerned about the safety of the population. Chris Gunness of the UN Relief and Works agency said: 'The situation in Yarmouk is an affront to the humanity of all of us, a source of universal shame. 'Yarmouk is a test, a challenge for the international community. We must not fail. The credibility of the international system itself is at stake.' The Syrian Observatory for Human Rights warned that the population of the camp are under threat of death from Isis, hunger and disease. Hatra is 68 miles southwest of the city of Mosul. It dates back 2,000 years to the Seleucid empire which controlled a large part of the ancient world conquered by Alexander the Great. It is famous for its striking pillared temple at the centre of a sprawling archaeological site. The ancient city, a UNESCO world heritage site, is said to have withstood invasions by the Romans thanks to its high, thick walls reinforced by towers. A temple to the Shamash sun god still stands more than 1,750 years after the Sassanian empire razed the Mesopotamian city. The ancient trading centre in Hatra spanned 4 miles in circumference and was supported by more than 160 towers. At its heart are a series of temples with a grand temple at the center — a structure supported by columns that once rose to 100 feet.
