Mohamed Alhakim claimed that dozens of bodies with surgical incisions and missing body parts have been found in shallow mass graves near ISIS stronghold Mosul over the past few weeks.

ISIS' horrifying trade in human organs, which was revealed by MailOnline last December, is just the latest way for the terrorist organisation to finance its activities, with other major sources of the group's $2 million-a-day income being the sale of oil, ransom payments, and smuggled antiques.

Speaking of ISIS' organ harvesting operations, Mr Alhakim said: 'We have bodies. Come and examine them. It is clear they are missing certain parts.'

He also said a dozen doctors have been 'executed' in Mosul for refusing to participate in organ harvesting.

Mr Alhakim briefed the UN Security Council on the overall situation in Iraq and accused ISIS of 'crimes of genocide' in targeting certain ethnic groups.

The outgoing UN envoy to Iraq, Nikolay Mladenov, also told the council that last month alone, 790 people were killed by terrorism and armed conflict in the country. 

He also noted the increasing number of reports and allegations that IS is using organ harvesting as a financing method, but he said only that 'it's very clear that the tactics ISIL is using expand by the day'. He used an acronym for the group.

Mr Mladenov said Iraq's most pressing goal is to win back the vast territory that ISIS has seized over the past year. 

The Sunni militants currently controls around a third of both Iraq and neighbouring Syria and imposed its strict interpretation of Sharia law in its self-declared caliphate  - subjecting a population of around four million people to a brutal campaign of rape and massacre.

'Especially worrying is the increasing number of reports of revenge attacks committed particularly against members of the Sunni community in areas liberated from ISIL control,' Mr Mladenov said, using an alternative acronym for the group known as ISIS in the West and Daesh in Arab nations.

The shocking news of ISIS trade in human organs was first revealed in a report by al-Monitor news website in December, citing an Iraqi ear, nose and throat doctor named Siruwan al-Mosuli.

He told the site that ISIS commanders hired foreign doctors to run an extensive organ trafficking system from a hospital in Mosul that is already beginning to generate huge profits. 

The al-Monitor report also claims the terror organisation has even set up a specialist organ-smuggling division whose sole responsibility is to sell human hearts, livers and kidneys on the lucrative international black market.

'[Al-Mosuli] said that lately he noticed unusual movement within medical facilities in Mosul Arab and foreign surgeons were hired, but prohibited from mixing with local doctors,' the report's author wrote. 'Information then leaked about organ selling.'

The report went on: 'Surgeries take place within a hospital and organs are quickly transported through networks specialized in trafficking human organs. Mosuli said that the organs come from fallen fighters who were quickly transported to the hospital, injured people who were abandoned or individuals who were kidnapped.'

Most of the organs are then smuggled out of Syria and Iraq into neighboring countries like Saudi Arabia or Turkey where criminal gangs sell them on to shady buyers across the globe, the Assyrian International News Agency reported.

While organ harvesting may be the most shocking of IS' revenue streams, the report highlights a string of others that contribute to the group's $2million annual income.
