Islamic State terror group kills 12 people in Syria's Palmyra city

"This destruction is a new war crime and an huge loss for the Syrian people and for humanity", Irina Bokova, director general of the United Nations cultural agency, said in a statement following reports that IS destroyed Palmyra's tetrapylon monument and the facade of the city's Roman amphitheatre.

SICK ISIS thugs have destroyed part of the iconic amphitheatre in the ancient Syrian city of Palmyra after retaking it from government forces.

But the jihadis recaptured the city in December, fighting their way into the town via several military bases, forcing government forces to retreat to the south.

Russian and Syrian forces have been unsuccessful in their attempts to hold the city after pushing ISIS militants out in March.

The group is known to have destroyed other monuments before they were forced out by a Russian-backed government offensive.

The terrorists also demolished Palmyra's famous Tetrapylon, a four-column structure.

"For example, as they pulled out of the campus of Mosul University, they burned campus buildings", Danti said.

He said that just two of the of the Tetrapylon's 16 columns remain standing.

The group this week destroyed monuments including part of a preserved Roman theatre and a tetrapylon, a series of pillars near the entrance to the city.

"Yesterday (Thursday), we received satellite photographs from our colleagues at Boston University showing damage to the facade of the Roman amphitheatre", he added.

But the group reportedly loots antiquities for profit, and as Washington Post reporter Liz Sly told Morning Edition in 2015, ISIS gets "masses of publicity every time they blow up or destroy something that is valued by the world".

"ISIS does this just to provoke the worldwide community".
