A senior Iranian official has issued a stark warning to the United States, urging an end to its blockade of Iranian ports and signalling Tehran’s readiness for further military confrontation.

Mohsen Rezaei, member of Iran’s Expediency Council and former commander of the Islamic Revolutionary Guard Corps, made the remarks during a televised address on state media.

“We advise the US military to end the siege before the Sea of Oman becomes your graveyard,” Rezaei said.

Rezaei described the US naval blockade, which began on April 13, as an “act of war” and insisted that Iran has the right to respond.

He also warned that the longer the blockade continues, the greater the potential damage to other countries in the region.

On ongoing diplomatic efforts to end the conflict, Rezaei stressed that the US must prove its trustworthiness through actions, not words.

“It is America that must prove itself now,” he said.

“Our armed forces have their finger on the trigger, and, at the same time, diplomacy continues.”

Iran has repeatedly rejected US demands to negotiate on Washington’s terms, and the blockade is expected to remain in place until Tehran agrees to a peace deal, according to US officials.
