A French satellite system has imaged the destroyed Temple of Baalshamin at Palmyra in Syria.

The ancient building, which dates to the 1st Century AD, was blown up by Islamic State militants.

The "before" image was acquired on 22 May by the Pléiades Earth-observation system, which is managed by Airbus Defence and Space.

The "after" view comes from 25 August. Even with the slight difference in angle, it is clear the temple has gone.

The UN training and research agency (Unitar) said its satellite system had also confirmed the destruction of the temple.

"It has been flattened," spokesman Einar Bjorgo told AFP news agency.

IS took control of Palmyra in May, sparking fears for the Unesco World Heritage site. The group's fighters had previously levelled a number of ancient monuments in Iraq.

The militants believe any shrines or statues implying the existence of another deity are sacrilege and idolatry, and should be torn down.

Unesco has called the deliberate destruction of Syria's cultural heritage a war crime.

Its director-general, Irina Bokova, accused IS of seeking to "deprive the Syrian people of its knowledge, its identity and history".
