Further clues have emerged that that the looting of museums following the 2003 invasion of Iraq wasn’t really the result of lax security or random looters from the street. It was probably a systematic inside job by an organized syndicate of corrupt Baathist officials before they went underground. The antiquities they stole were either sold to help fund the insurgency or were kept by former officials who later joined AQI which became ISIS.
At least the Washington Post reported on the discovery (h/t MFS001), although it buried the most important connection in paragraph 15 of a 17 paragraph article (in bold below, emphasis mine):
Artifacts looted during the Iraq invasion turned up in the house of an Islamic State leader
BAGHDAD — The United States handed over more than 400 ancient artifacts to Iraq on Wednesday, part of ongoing efforts to repatriate the country’s looted heritage. But this latest batch has a particularly intriguing back story — the antiquities were seized by U.S. Special Operations forces members as they raided the house of a leader of the Islamic State militant group.
The nighttime operation to capture the militant took place in eastern Syria in May, and the Delta Force troops did not come back with their prize. It was their first such ground mission in the country, and their main target, a man known as Abu Sayyaf who ran oil operations for the Islamic State in the area, was killed in an ensuing firefight.
But as the commandos scoured the compound for documents and laptops that could provide intelligence about the organization, they stumbled across artifacts thought to be dating back as far as 4,000 years.
Among them was a religious text written in Aramaic, the ancient Semitic language said to have been spoken by Jesus. An official at the National Museum of Iraq in Baghdad said Wednesday that it was about 500 years old but has not yet been properly dated. (Museum officials also said that, as with many of the items found, they could not be sure whether the text was of Syrian or Iraqi origin.)
There were hundreds of coins — some of them gold from the Abbassid era, others silver pieces from the Umayyad period. There were stone cylindrical seals from the ancient city of Nimrud and fragments of pottery.
The presence of the artifacts in Abu Sayyaf’s house is perhaps not surprising. The Islamic State’s “Diwan al-Rikaz” — a ministry overseeing precious resources — has departments in charge of both oil and gas and antiquities. Abu Sayyaf may well have had a role in the sale of these resources…
…Among the items found in the house were three Babylonian stone seals, which officials said were stolen in 2003 from the National Museum of Iraq in Baghdad during the chaos that followed the U.S.-led invasion of Iraq. Their museum numbering is still visible…
