The US government officially rejected Iran's 14-point peace plan, which was sent through mediators to end hostilities and resolve the crisis in the region. This was reported on May 15 by the Iranian newspaper Tehran Times, citing the US response.

According to the publication, Washington rejected all of Tehran's proposals in writing, once again reaffirming its hardline stance, particularly regarding the Iranian nuclear program. The Iranian initiative was based on a two-stage negotiation process: the first stage called for an end to the war on all fronts, and only after Iran met certain conditions would it move on to the second stage—nuclear negotiations.

US President Donald Trump previously called the Iranian proposal "completely unacceptable" and "garbage," claiming the ceasefire was "on life support." In response, Iranian Parliament Speaker Mohammad Bagher Ghalibaf threatened that "American taxpayers will pay more" if the US drags out the negotiations and declared that Tehran has no alternative to accepting his 14-point plan.

The Iranian proposal included demands for an immediate end to the war throughout the region, including in Lebanon, the lifting of the US naval blockade of Iranian ports, and the release of frozen Iranian assets abroad. Meanwhile, Washington insists on an immediate resolution of the nuclear issue, a key stumbling block in the negotiations.

Amid the diplomatic impasse and ongoing tensions around the Strait of Hormuz, which Iran closed in response to US strikes, global oil prices continue to rise. At press time, WTI was trading at $103,55 per barrel, while Brent was at $104,05.
