Since the beginning of the war, US President Donald Trump has repeatedly demanded that Iran not be allowed to enrich uranium, saying there is a risk the country could develop nuclear weapons.
The disagreement between the United States and Iran over the nuclear issue was the stumbling block that caused the historic negotiations in the Pakistani capital Islamabad to collapse.
Iran may consider agreeing to a five-year ban on uranium enrichment. The United States rejected the offer and is demanding a halt to enrichment for at least 20 years, according to two Iranian sources and one American source - all with knowledge of the negotiations, The New York Times reports.
Despite the US blockade of the Strait of Hormuz and Iran's threats of retaliation over the blockade, a second round of talks between the US and Iran is reportedly on the cards, according to sources in Pakistan's mediation delegation. US President Donald Trump reportedly said that Iran "wants to work on a deal."
The ambition is for details of a second meeting between the US and Iranian delegations to be decided before the temporary ceasefire expires next week, CNN reports.
Pakistan has mediated the negotiations between the US and Iran.
