The United States has announced new sanctions on over 25 individuals and companies including a number of Iranian banks, financial institutions, and aviation companies as well as a number of foreign companies.

The U.S. maintains that the sanctions were approved by the U.S. Treasury in an attempt to maintain pressure on Iran. It says the new additions to the list are involved in assisting Iran’s nuclear program or avoiding sanctions. Providing assistance to the Syrian regime is also cited as a reason for imposing sanctions on some of the entities.

The new sanctions were announced on Friday August 29 by Caitlin Hayden, spokeswoman for the White House National Security Council, who said: “Just as we announce these measures and continue to enforce pre-existing sanctions on Iran, the United States remains committed to working with our P5+1 partners toward a long-term, comprehensive solution that provides confidence that Iran's nuclear program is exclusively peaceful.”

The nuclear negotiations between Iran and the 5+1 are set to continue in November.
