US president Barack Obama says he hopes new international sanctions against Iran’s nuclear program can be imposed within weeks.
The West suspects Iran of trying to acquire nuclear weapons.
With French president Nicolas Sarkozy by his side, Mr Obama declared the US is determined to pursue strong sanctions against Iran, and soon.
“I’m not interested in waiting months for a sanctions regime to be in place,” Mr Obama said.
“I’m interested in seeing that regime in place in weeks.”
Speaking through an interpreter, Mr Sarkozy has backed the US stance.
“The time has come to take decisions. Iran cannot continue its mad race,” he said.
But Mr Obama says there is no agreement yet on the new sanctions.
