Iran has conveyed its ​response to the ‌US proposal for ending the war ​to intermediary Pakistan, rejecting ​a ceasefire and emphasising ⁠the necessity ​of a permanent end ​to the war, the official IRNA news ​agency said on ​Monday.

The Iranian response consisted of 10 clauses, including an end to conflicts in the region, a protocol for safe passage through the Strait of Hormuz, lifting of sanctions, and reconstruction, the agency added.

US President Donald Trump, who has threatened to rain “hell” on Tehran if it did not make a deal by 8pm EDT Tuesday (midnight GMT) to open the vital route for global energy supplies, rejected the Iranian proposal on Monday and said his deadline was final.

“They made a proposal, and it’s a significant proposal. It’s a significant step. It’s not good enough,” Trump told reporters at an annual White House Easter event, referring to Iran.

Iran responded to US and Israeli attacks in February by effectively closing Hormuz, a conduit for about a fifth of the world’s oil and natural gas supply. The waterway’s stranglehold on the global economy has proved a powerful Iranian bargaining chip, and on Monday, it showed reluctance to relinquish it too easily.

Iran’s foreign ministry spokesperson Esmaeil Baghaei said on Monday that Tehran’s demands “should not be interpreted as a sign of compromise, but rather as a reflection of its confidence in defending its positions.” He added that earlier US demands, such as a 15-point plan, were rejected as “excessive”.

Ceasefire proposal ‘one of many ideas’

A White House official told Reuters that Washington’s ceasefire proposal was “one of many ideas, and (Trump) has not signed off on it. Operation Epic Fury continues”.

In a post laden with expletives on his Truth Social platform on Sunday, Trump threatened further strikes on Iranian energy and transport infrastructure if Iran failed to make a deal and reopen the Strait by Tuesday.

Anwar Gargash, an adviser to the president of the United Arab Emirates, said any settlement must guarantee access through Hormuz. He warned that a deal that failed to rein in Iran’s nuclear programme and its missiles and drones would pave the way for “a more dangerous, more volatile Middle East”.

Fresh aerial strikes were reported across the region on Monday, more than five weeks since the US and Israel began pounding Iran in a war that has killed thousands and damaged economies by sending oil prices surging.

Iranian state media said the Revolutionary Guards’ intelligence chief, Majid Khademi, had been assassinated. Israel on Monday claimed responsibility for his assassination.

A US-Israeli attack hit the data centre at Sharif University of Technology in Tehran, damaging infrastructure underpinning the country’s national artificial intelligence platform and thousands of other services, Fars News Agency said on Sunday.
