IS to destroy more of Palmyra in Syria

ISIS' vandalism of one of Syria's most important historic sites looks set to escalate as Russian intelligence suggests that the militant group plans to wreak more destruction on the ancient Roman ruins at Palmyra.

The city has seen many of its irreplaceable antiquities, monuments and historic sites destroyed since the terror group first occupied it in May 2015.

Russia's Defense Ministry released a statement yesterday saying they have detected "an upsurge in truck movement" near the ancient site that indicates that ISIS is planning to cause even more damage to the ancient complex, reported CNN.

"We have detected an upsurge in truck movement near the ancient city amid Syrian troops' successful advance on Palmyra," the statement reads. "This indicates that Daesh (ISIS) wants to bring in explosives to deal maximum damage to the remaining architectural relics before they leave."

Footage from a Russian Unmanned Aerial Vehicle shows the uptick in movement from ISIS' trucks in the region, showing "ISIS intentions to deliver explosives in order to cause maximum damage to the leaving architectural monuments before their retreat." The same footage also shows the destruction already wrought by the group, including the facade of the Roman theater and Tetrapylon column along with the Temple of Baalshamin, Temple of Bel and other sites.
