Iran said the latest US proposal has partly bridged the gap between the warring sides as they seek to turn a fragile ceasefire into a peace deal.

According to a Bloomberg report, Tehran is in the process of responding to a text submitted by the US, which “has narrowed the gaps to some extent,” the semi-official Iranian Students’ News Agency reported on Thursday, without saying where it got the information. “Further narrowing requires an end to the temptation for war on Washington’s part.”

Trump’s commentaries on the war have continuously whiplashed between diplomacy and threats this week. On Monday, he said he has put any attack on Iran on hold on request from Middle-East leaders but on Tuesday told reporters he had been “an hour away from making the decision” to resume attacks. 

According to a Financial Times report, Secretary of State Marco Rubio highlighted "some good signs" regarding a potential agreement. The report indicates that Pakistani mediators are anticipated to arrive in Tehran today. Meanwhile, Iranian President Masoud Pezeshkian has maintained a firm stance, declaring that the country "will never back down".

U.S. crude oil fell nearly 2% to close at $96.35 per barrel. International benchmark Brent crude fell more than 2% to settle at $102.58.  as per data from CNBC. 

Alternatively, Reuters reported earlier today that Iran’s supreme leader issued a directive to keep enriched uranium within the country, according to sources, which dampened investor sentiment in early trading.

In other news, the U.S. Department of Commerce will award the grants up to $2 billion to nine quantum computing companies in deals that also include U.S. government equity stakes, according to a Wall Street Journal report. 

IBM will account for half of the total $2 billion grants being awarded by the Trump administration. Rigetti Computing, GlobalFoundries, and Infleqtion were among other quantum computing companies that will receive the grant.
