The sanctions are part of the Trump administrations' decision to pull out of a deal aimed at preventing Iran's development of nuclear weapons.

More sanctions, mostly involving energy and shipping, will take effect November 4.

The Turkish lira hit a fresh record low against the US dollar on Monday amid rising tensions with the United States. The US Treasury Department placed sanctions last week on Turkey's ministers of justice and interior over the detention of pastor Andrew Brunson.
