Iran has denounced new sanctions imposed by the US over its ballistic missile programme.
The sanctions had "no legal or moral legitimacy", a foreign ministry spokesman said.
In October, Iran tested a precision-guided ballistic missile capable of delivering a nuclear warhead, in defiance of a UN ban.
The US move came after global economic sanctions on Iran were lifted in line with a deal on its nuclear programme.
The new US Treasury sanctions prevent 11 entities and individuals linked to the programme from using the US banking system.

Announcing the measures, Adam J Szubin, US acting under-secretary for terrorism and financial intelligence, said: "Iran's ballistic missile programme poses a significant threat to regional and global security, and it will continue to be subject to international sanctions."
However, Iranian foreign ministry spokesman Hossein Jaber Ansari said on Monday: "Iran's missile programme has never been designed to be capable of carrying nuclear weapons."
He said: "The US sanctions against Iran's ballistic missile programme... have no legal or moral legitimacy."
Mr Ansari added: "America sells tens of billions of dollars of weaponry each year to countries in the region. These weapons are used in war crimes against Palestinian, Lebanese and most recently Yemeni citizens.
