The President of the United States of America, Barack Obama, has defended the recently concluded deal with Iran, which would see an easing of sanctions the country in return for some concessions by Teheran on its nuclear programme.
"Huge challenges remain, but we cannot close the door on diplomacy, and we cannot rule out peaceful solutions to the world's problems," Obama said in San Francisco.
"We cannot commit ourselves to an endless cycle of violence, and tough talk and bluster may be the easy thing to do politically, but it's not the right thing for our security."
Meanwhile French Foreign Minister Laurent Faubius said that some EU sanctions on Iran could be lifted in December.
Mr Fabius told French media that "Iran is committed to giving up the prospect of nuclear weapons. It's perfectly clear".
Saudi Arabia also cautiously welcomed the deal.
"This agreement could be a first step towards a comprehensive solution for Iran's nuclear programme, if there are good intentions," a statement said.
