AhlulBayt News Agency - ISIS extremists have threatened to destroy the Egyptian pyramids - after releasing a video purporting to show fighters blowing up a 2,500-year-old temple in Iraq.
Footage shows a militant vowing to demolish the temple of Nabu in the ancient Assyrian city of Nimrud - before a massive explosion reduces a building to rubble.
The final scene in the ten-minute video shows the Great Pyramid of Giza near Egypt's capital, Cairo and a fanatic pledging to blow up 'ancient sites built by the infidels'.
It is not known when ISIS targeted the Nabu temple - which was dedicated to the Babylonian god of wisdom, reports Vocativ, which sourced the video from online forums.
Video shows information signs on the temple wall before the explosion is shown from a number of different angles.
ISIS also claim to show bulldozers destroying the Adad and Mashki gates at Nineveh, near Mosul.
Earlier this year, shocking pictures showed how ISIS militants had destroyed ancient monuments in the Syrian city of Palmyra.
The militants sparked a global outcry when they started destroying Palmyra's treasured monuments, which they consider idolatrous, after taking the city in May 2015.
They ransacked UNESCO World Heritage sites before finally being ousted after three weeks of fighting earlier this year.
Heads were sledgehammered off sculptures while priceless carvings were ripped off walls of museums during the terror group's devastating occupation of the city.
Extremists wrecked a number of important structures on the site, including the Temple of Baal, leaving experts with a difficult task of re-constructing the ancient landmarks.
