Iran will respond if the U.S. government passes new sanctions, deputy foreign minister Abbas Araqchi said Wednesday, according to state media.

New sanctions being discussed in the U.S. Congress are "a completely clear hostile act and against the Islamic Republic of Iran and ... will be met with a definitive response," Araqchi, who is also a top nuclear negotiator, was quoted as saying by the Islamic Republic News Agency (IRNA).

He did not specify what actions Iran would take.

The U.S. House of Representatives voted overwhelmingly on Tuesday to slap new sanctions on Iran, Russia and North Korea. The Republican-controlled Senate passed an earlier version of the bill with near-unanimous support.
