The US has announced fresh sanctions against Iran over its ballistic missile programme and what it says is Iran's support for terror organisations.
The US state department said 18 entities or individuals would be affected by the new measures.
It said all 18 had supported Iran's ballistic missile programme or the elite Republican Guards Corps.
The statement also criticised Iran's support for the Syrian government and groups such as Hezbollah and Hamas.
It also accused Iran of prolonging the conflict in Yemen by providing support for Houthi rebels. Iran has vowed to retaliate against the new sanctions.
