Pakistan and Egypt are among the countries channeling communications between US and Iranian officials, a Pakistani official source told CNN on Sunday.
The news comes as US President Donald Trump set a new deadline for Iran to open the Strait of Hormuz before the United States begins targeting Iranian power facilities, stating Iran has until Tuesday at 8:00 p.m. Eastern time to agree to a deal.
In an earlier post, Trump intensified threats against Iran, warning that civilian infrastructure could be targeted beginning Tuesday if the Strait of Hormuz is not reopened.
"Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran. There will be nothing like it!!!" Trump wrote on Truth Social.
He further warned: "Open the ***** Strait, you crazy bastards, or you’ll be living in Hell - JUST WATCH! Praise be to Allah. President DONALD J. TRUMP."
Trump told Axios on Sunday that his special envoys Steve Witkoff and Jared Kushner are in negotiations with Iran.
Pakistan’s foreign ministry said in a social media post on Saturday that Foreign Minister Mohammed Ishaq Dar had spoken with his Iranian counterpart Abbas Araghchi.
During the call, Dar “reiterated Pakistan’s support for all efforts aimed at de-escalation and underscored the importance of resolving issues through dialogue and diplomacy."
Pakistan had previously mediated talks between the US and Iran.
Meanwhile, the Iranian Revolutionary Guard Corps (IRGC) rejected Trump’s ultimatum for Iran to reopen the Strait of Hormuz by Tuesday.
“The Strait of Hormuz will never return to its previous state, especially for the US and Israel," the IRGC Navy Commander declared, as quoted in a social media account representing the IRGC Navy Command.
“The IRGC Navy is completing the operational preparations of the plan issued by Iranian officials for a new order in the Persian Gulf," the Commander declared.
Mohammad Bagher Ghalibaf, the Speaker of the Iranian parliament and former commander of the air force, rejected Trump's ultimatum and threatened to further escalate the situation in the region.
“Your reckless moves are dragging the United States into a living HELL for every single family, and our whole region is going to burn because you insist on following Netanyahu’s commands," Ghalibaf wrote in a post on social media.
"Make no mistake: You won’t gain anything through war crimes. The only real solution is respecting the rights of the Iranian people and ending this dangerous game," he added.
