The National Bank of Ukraine has appealed to Himamauli Das, Acting Director of the Financial Crimes Enforcement Network (FinCEN), to initiate preventive investigations into tax residents and businesses controlled by Russian residents around the world in order to prevent the spread of international terrorism, the regulator's press service said on Saturday.

"Russia's war against Ukraine is accompanied by horrific terrorist acts that are killing Ukrainian civilians… But until that happens, it is our duty to convince you to take preemptive measures to prevent the death toll among civilians from rising further," the press service of NBU Deputy Governor Serhiy Nikolaychuk said.

The NBU also urged FinCEN to warn banks and other financial institutions (based in the United States, the UK, Switzerland, the EU countries, etc.) that are servicing Russian capital about possible sanctions against them as potential accomplices in the financing of international terrorism.
