The apparent breakthrough in negotiations comes after Iran exchanged fire with the US and Israel over three days this week, threatening to return the Middle East to full-scale war.
Earlier on Thursday, US President Donald Trump said that a deal to end the war with Iran is nearly complete and is expected to be signed over the weekend in Europe, as he called off military strikes on the Islamic Republic hours after threatening to take control of its oil industry.
Trump, speaking to reporters at the Oval office on Thursday afternoon, said Vice President JD Vance is expected to attend the signing ceremony which could take place in Europe as soon as this weekend.
The US president said he spoke to leaders of Middle Eastern countries, including Qatar, the UAE, Saudi Arabia, Bahrain, Kuwait and Pakistan, regarding the latest round of negotiations.
Later, addressing a tele-rally in favour of Georgia Lt Governor Burt Jones, who is running for the post of Governor, Trump declared that the US has ended the war with Iran.
