伊斯兰国组织的激进分子据报摧毁了叙利亚古城帕尔米拉的又一个稀世古迹。
活动人士说，该组织把城里的凯旋门炸得“粉碎”。
叙利亚人权观察说，凯旋门存放了被激进分子视为亵渎神灵的装饰物。
卫星图像证实这则消息。这将是伊斯兰国组织自今年5月夺取帕尔米拉城以来所摧毁的第三个古迹。
目前已经有两座古罗马时期的神庙被炸毁。
极端分子认为这些历史古迹和图画亵渎神灵。联合国和历史学家认为毁坏古迹是战争罪。
Islamic State militants have reportedly destroyed another irreplaceable ancient artifact in the ancient Syrian city of Palmyra.
Activists say Islamic State blew up the city's Arch of Triumph, describing it has having been "pulverized."
The Syrian Observatory for Human Rights says the arch had ornaments that Islamic State militants considered blasphemous.
If the destruction is confirmed by satellite images, it would be the third ancient site destroyed since the Islamic State group seized Palmyra in May.
Two Roman-era temples already have been blown up.
The extremists consider ancient historic artifacts and images to be blasphemous. The United Nations and historians regard such actions to be war crimes.
