US sanctions on Iranian metals are against international norms, Iran's foreign ministry spokesman said on Thursday, warning that Washington would be responsible for Iran's losses.
"This US measure is against the international commitments of this regime... It is against international norms ... The United States will be responsible for the caused losses," Abbas Mousavi was quoted as saying by the semi-official news agency ISNA.
US President Donald Trump on Wednesday imposed new sanctions on Iran, targeting revenue from its exports of industrial metals.
