US President Barack Obama has defended the conclusion of nuclear negotiations between the P5+1 group of countries and Iran, PressTV reported.
"When deal is implemented, we will know we have dismantled immediate concerns around Iran's nuclear program," he told reporters on Wednesday.
He added this is the "most vigorous inspection and verification regime by far that has ever been negotiated."
Iran and the P5+1 group of countries -- the US, Britain, France, China, Russia and Germany -- reached a conclusion on the Joint Comprehensive Plan of Action (JCPOA) in the Austrian capital of Vienna on Tuesday.
