President Barack Obama says he has spoken by phone with Iranian president Hassan Rouhani.
It is the first conversation between American and Iranian presidents in more than 30 years.
Mr Obama says after speaking with Mr Rouhani, he believes the US and Iran can reach a comprehensive solution over Iran's nuclear programme.
The US president says he and Mr Rouhani have both directed their teams to work quickly to pursue an agreement.
He says the US will co-ordinate closely with its allies, including Israel, which considers an Iranian nuclear weapon capability to be an existential threat.
Mr Obama says the conversation shows the possibility of moving forward.
Iranian and UN officials have been meeting to continue talks on how to investigate suspicions that Iran has worked secretly on trying to develop nuclear weapons. Tehran denies that claim.
