UN confirms destruction of Temple of Bel in Palmyra
IS militants seized control of Palmyra in May, sparking fears for the World Heritage site.
A satellite image confirms that the main temple in the ancient city of Palmyra in northern Syria has been destroyed, the United Nations says.
There had been earlier reports of an explosion at the Temple of Bel in Palmyra, which is held by militants from the Islamic State group.
Syria's antiquities chief had earlier said the basic structure of the 2,000-year-old site was intact.
But UN satellite analysts Unosat say the image shows almost nothing remains.
On Monday, Maamoun Abdulkarim, the head of the Syrian Department of Antiquities and Museums, had said the Temple of Bel suffered a large explosion, but that he believed most of the site had remained intact.
Witnesses had struggled, however, to get close to the site to confirm the extent of the damage.
IS has previously targeted historical sites in areas under its control in Iraq and Syria, regarding their ancient temples and sculptures as heretical.
Last week, it was confirmed that another site at Palmyra, the Temple of Baalshamin, had been blown up.
Unosat released satellite images on Monday showing the extent of the damage to the Baalshamin temple, proving that parts were heavily damaged or completely destroyed.
IS militants seized control of Palmyra in May, sparking fears for the World Heritage site.
Earlier this month the group murdered 81-year-old Khaled al-Asaad, the archaeologist who had looked after the Palmyra ruins for 40 years.
