According to media reports on 15 May 2015, extremist Islamic State (IS) militia is advancing towards Palmyra, raising fears that the militants will destroy the historic site. Palmyra is believed to be founded by King Solomon. It was long a trade center that boomed with the decline of Petra in modern-day Jordan. The city, 240 kilometers (150 miles) northeast of Damascus, emerged to become a powerful state after the Romans took control, serving as a link between the ancient Orient and Mediterranean countries.
