Iran's government said that peace talks with the United States, brokered by Pakistan, concluded after 14 hours of negotiations. The talks began on Saturday and went on well beyond midnight, according to Pakistan local time.
The talks will continue on Sunday as both countries did not reach any understanding on their differences in the last round of talks, said Iran's local media.
A major flashpoint emerged as the Strait of Hormuz, with the United States and Iran failing to reach an understanding over the key waterway's control.
The United States Centcom said that two Navy warships passed through the Strait of Hormuz to start clearing mines, but the claim was denied by the Iranian forces.
US President Donald Trump maintained that the United States has won the war and said that whether the two countries reach a deal or not 'makes no difference' to him.
