A bank has maintained an account for a European charity for several years.

The charity frequently withdrawing cash from the bank indicates possible terrorist financing, as cash transactions are often used to conceal the source, destination, and purpose of funds. Cash transactions also make it difficult to trace the flow of funds and identify the beneficiaries. Terrorist financiers may use charities as a cover to collect and distribute funds for their activities, and may exploit the cash-based nature of charitable donations to avoid detection12.
