Islamic State releases video showing 'destruction of Nimrud'
Islamic State have released footage of militants smashing artifacts in the ancient city of Nimrud in northern Iraq before showing a massive explosion which is thought to have levelled the site.
Nimrud, which is shown being blown up in the jihadist video, was once the jewel of Assyria, home to a treasure considered one of the biggest archaeological finds of the 20th century.
The subsequent footage shows a massive explosion and its aftermath, suggesting the ruins of Nimrud- which lie on the Tigris about 30 kilometres southeast of Mosul - were largely levelled.
Nimrud, founded in the 13th century BC, is one of the most famous archaeological sites in a country often described as "the cradle of civilisation".
"Nimrud was the capital of Assyria, during the new Assyrian era," said Abdulamir Hamdani, an archaeologist from Stony Brook University in New York.

The city, which is on UNESCO's tentative list of world heritage sites, is the later Arab name given to a settlement which was originally called Kalhu.
Most of Nimrud's priceless artefacts were moved long ago to museums in Mosul, Baghdad, Paris, London and elsewhere but giant "lamassu" statues - winged bulls with human heads - and reliefs were still on site.
Destruction using bulldozers at Nimrud was first reported in early March, a week after another IS video showed militants wielding sledgehammers are seen gleefully smashing statues in the Mosul museum.

Many of the artefacts destroyed in the video came from Nimrud.
"It's really a very important site in the history of Mesopotamia," said Hamdani.
"Many of Assyria's greatest artistic treasures came from this site."
The "treasure of Nimrud", unearthed in 1988, is a collection of 613 precious stones, gold jewels and various ornaments which some archaeologists described as the most significant discovery since Tutankhamun's tomb in Egypt in 1923.

The treasure, which dates back to the Assyrian empire's heyday around 2,800 years ago, was briefly displayed at the National Museum in Baghdad before Iraq invaded Kuwait.
It was then hidden and its fate remained unknown until it was discovered in 2003, soon after US-led troops toppled Saddam Hussein's regime, in a bombed out central bank building.
