The Islamic State group, also known as ISIS or ISIL, has murdered a Syrian antiquities expert and museum director after he refused to lead them to ancient treasures the terrorist group reportedly sought to destroy. ISIS, which has taken over swaths of territory in Iraq and Syria in the hopes of establishing a state that adheres to strict Muslim law, publicly executed Khaled al-Asaad, who worked as a professor and held the title of general manager for Palmyra, one of Syria's most ancient sites and museum, according to the Syrian Observatory for Human Rights. The scholar was murdered in front of a crowd on Tuesday in Palmyra's square. ISIS has controlled the city since mid-May, according to The Wall Street Journal. He had been captured and held prisoner by ISIS for more than a month before he was beheaded. Al-Asaad had spent much of his life overseeing precious artifacts from one of the oldest civilizations in the world. Palmyra contains the monumental ruins of a city that, between the first and second centuries, was the cultural center of the Middle East. The site was declared a UNESCO World Heritage site in 1980. He was executed after he reportedly refused to lead his captors to the historical sites they sought to destroy, The Guardian reports. ISIS fighters have been targeting and obliterating ancient artifacts, including collections found in Iraq's Mosul Museum in February and tombs near Palmyra in June. Scholars and friends around the world have taken to social media to decry al-Asaad's murder.

The real heroes saving Syria's Cultural heritage are the women/men risking their lives daily inside Syria. All we can do is support them.
