Viktor Ivanov made the disclosure on Friday saying large quantities of poppy, which is used to produce heroin, are being transported through ISIL-controlled areas in Iraq to Europe.
Ivanov added that over half of Europe’s heroin supplies come from the terrorist group through the Iraqi territory, parts of which is under ISIL control.
The FSKN head urged the United Nations (UN) to discuss the issue, saying "this is a threat not only to our country, but also European security.”
According to Ivanov, the money from drug trafficking is likely becoming a "huge financial sponsorship” for the ISIL.
In addition to drug trafficking, the sale of oil and antiquities as well as ransom from abductions are three other sources of revenue for the ISIL.
Furthermore, reports indicate that wealthy individuals in the Persian Gulf region have raised a major amount of fund for terrorists.
The report comes as the UN adopted a Russian-drafted resolution aimed at cutting funding to the ISIL, the al-Qaeda-affiliated al-Nusra Front and other al-Qaeda-linked groups last month.
The resolution urges countries not to buy oil or antiquities from the terrorists and refrain from paying them ransoms and if any individual or state is involved in such activities with the terrorists, they must be charged as accomplices of terrorists.
Experts have estimated the terrorists’ daily income from illegal sales at 2-3 million dollars. In addition, a UN report published last November stated that the ISIL makes approximately USD 96,000 to USD 123,000 per day from ransom payments.
The ISIL terrorists have seized swathes of land in Iraq and Syria. They have also extended their terror activities to the Libyan soil in recent weeks.
They are engaged in crimes against humanity in the areas under their control.
