The Takfiri ISIL terrorist group has released a new gruesome video which purportedly shows mass execution of 25 Syrian soldiers in the ancient city of Palmyra.
In the footage that emerged on Saturday, the executioners that seem to be teenagers shoot dead the soldiers dressed in green and brown military uniforms on the stage of the city's amphitheater.
A relatively small number of men and children are seen watching the carnage from the ancient theater's seats.
The ISIL terrorists captured Palmyra, which is on the list of UNESCO's World Heritage sites and is located about 215 kilometers (133 miles) northeast of the capital, Damascus, on May 21.
The Takfiri group has reportedly carried out over 200 executions, including of civilians, in and around Palmyra.
The so-called Syrian Observatory for Human Rights reported the first executions in Palmyra on May 27.
Syria's antiquities director Mamoun Abdelkarim warned at the time that the killings were indicative of the start of "the group's barbarism and savagery against the ancient monuments of Palmyra."
"Using the Roman theater to execute people proves that these people are against humanity," he added.
ISIL has so far released several similar videos purportedly showing execution of its captives from different countries, including the United States, Britain, and Japan.
