There is also a duty under section 8(1) of the Terrorism (Suppression of Financing) Act for every person in Singapore and every citizen of Singapore outside Singapore who has (inter alia) information about any transaction or proposed transaction in respect of any property belonging to any terrorist or terrorist entity, to file a suspicious transaction report.
