In his phone conversation in Wednesday, Obama emphasized that it will be important for Iran to follow through on commitments made in the deal, the White House said.

Obama and the king agreed to talk regularly as negotiations continue on a longer-term agreement "that would resolve the international community's concerns regarding Iran's nuclear program," the White House said.

Saudi Arabia had given its qualified approval to the deal earlier this week.

Iran and the six major world powers sealed an interim deal in Geneva on Sunday morning to pave the way for the full resolution of the West’s decade-old dispute with Iran over the country’s nuclear energy program.

In exchange for Iran agreeing to limit certain aspects of its nuclear activities, the United States and its allies have agreed to lift some of the existing sanctions and let Tehran reap as much as $7 billion in relief from economic sanctions over six months.
