The Strait of Hormuz will remain shut until the US meets the conditions ​of an interim deal signed with Iran in June, the top ‌Iranian negotiator Mohammad Baqer Qalibaf said in comments published by state media on Tuesday.

These conditions include ​the US lifting its blockade of Iranian ports, lifting ​oil sanctions, releasing Tehran’s frozen assets, and ending threats and military operations on all fronts, Qalibaf told parliament.

The ​memorandum of understanding, clinched on June 17, quickly ​unravelled over a dispute about control of the Strait of Hormuz, the narrow waterway through which a fifth ​of global oil and liquefied natural gas ​flowed before the war.

US President Donald Trump said the ‌deal was “over” on July 7 and a week later Iran’s foreign ministry declared it “suspended”.

Under the MoU, Iran and the US had committed to ​negotiating a final ​deal — covering broader issues such as the fate of Iran’s nuclear programme — in ​a maximum of 60 days, extendable ​by mutual consent.

A senior Iranian official told Reuters on Monday that Iran would now shift to a “fully offensive” posture ⁠due ​to the stalled diplomatic ​efforts to secure a permanent end to the conflict.
