The United States will continue to target Iran's support for militant proxies even with a nuclear deal that lifts nuclear-related sanctions, a senior US Treasury official said on Wednesday.

It will take at least six to nine months for Iran to fulfill the necessary conditions for initial sanctions relief, said Adam Szubin, the US Treasury's acting under secretary for terrorism and financial intelligence, in testimony to a US Senate committee.

If Iran were to violate its commitments under a nuclear deal reached with world powers in July, US sanctions could be reimposed "in a matter of days," Szubin said.  - Reuters
