Reza Zarrab testifies against Turkish official in sanctions case

A Turkish gold trader has gone from being the target of a US investigation to the government’s star witness in a case that is straining relations between Washington and Ankara.

Reza Zarrab says he paid Turkey’s former economy minister Zafer Caglayan tens of millions of dollars in bribes to launder money on behalf of Iran, in violation of US sanctions.
