Pakistan has emerged as the lead mediator in efforts to end the US-Israeli war on Iran, but following a marathon first session of talks on 11 April, talks have stalled.
On Tuesday, Tehran accused the United States of violating the truce through its blockade of Iranian ports and seizure of a ship.
"By imposing a blockade and violating the ceasefire, Trump wants to turn this negotiating table into a surrender table or justify renewed hostilities, as he sees fit," said Iran's powerful parliament speaker Mohammad Bagher Ghalibaf, who headed the delegations to talks in the Pakistani capital two weeks ago.
"We do not accept negotiations under the shadow of threats, and in the last two weeks we have been preparing to show new cards on the battlefield," he wrote on X.
Iran's Revolutionary Guards warned of targeting any vessel attempting to pass through the Strait of Hormuz without permission.
