Iran has used a network of more than 5,000 secret military-linked agencies to import at least $2 billion worth of hardware, explosives and heavy-duty vehicles since January 2025, despite Western sanctions and a US naval blockade, a Reuters investigation has found. The agencies, whose names begin with the letters MOD, refer to Iran's Ministry of Defence. Reuters examined thousands of Iranian bank and government records, corporate filings, shipping documents and import data with Israeli-American risk consultancy 240 Analytics.
