At a White House reception, Obama said that it was important for the United States to test Iran's intentions, and pledged to keep working for a comprehensive deal over its peaceful nuclear activities.

Obama also vowed to keep striving for a final deal with Iran over the coming months.

Earlier, Israeli regime Prime Minister Benjamin Netanyahu harshly criticized an interim nuclear deal reached between Iran and world powers in Geneva last month.

Obama's critics on Capitol Hill have also questioned the president's tactics and are threatening to enact new sanctions against Iran, which the White House fears would scupper the talks.

The interim nuclear deal has recognized Iran nuclear enrichment for peaceful purposes and freezes the enrichment level to 5 percent in return for easing of the illogic sanctions imposed by the US and its allies against Iran.

“We cannot close the door on diplomacy, and we cannot rule out peaceful solutions to the world's problems," Obama said earlier, referred to the nuclear deal concluded over Iran nuclear case.

"We cannot commit ourselves to an endless cycle of conflict, and tough talk and bluster may be the easy thing to do politically, but it's not the right thing for our security," he added.
