The Islamic State continues to rely on logistics centers within Turkey for its finances, Ahval reported referring to US Treasury report.
According to the department, ISIS frequently collected and sent funds to intermediaries in Turkey who smuggled cash into Syria.
Ankara's commitment to fighting ISIS has been a topic of discussion for a while.
ISIS continued to use cash service businesses to move funds to and from Iraq and Syria, often relying on logistics centers in Turkey and other financial centers.
When the US launched a raid in the northwestern province of Syria in October 2019 to assassinate ISIS leader Abu Bakr al-Baghdadi, newly appointed National Security Council coordinator for the Middle East and North Africa Brett McGurk wrote an article for the Washington Post.
According to him, considering that al-Baghdadi's hideout was not far from a large Turkish military post, Ankara needs to explain something.
Former President Donald Trump thanked the Syrian Kurds for some of the support they were able to provide in the same operation.
ISIS probably has about $ 100 million in cash reserves spread across the region, a report added.
The US Treasury also noted that ISIS supporters are increasingly using cryptocurrencies, still relying on traditional methods of transferring funds to Iraq and Syria.
