Iran live updates: US blockade of Iran's Strait of Hormuz ports to begin Monday

Just before taking off to Islamabad, Pakistan, for negotiation talks with Iran, Vice President JD Vance told reporters he expects "positive" discussions.

"We're looking forward to the negotiation. I think it's going to be positive," Vance told reporters before boarding Air Force Two.

Despite the optimistic outlook, the vice president delivered a warning that the U.S. will not be "receptive" if the Iranians try to "play us."

"We'll foresee, as the President of the United States said, if the Iranians are willing to negotiate in good faith, we're certainly willing to extend the open hand. If they're going to try to play us, then they're going to find that the negotiating team is not that receptive," he said.

Vance added that President Donald Trump has given the American negotiating team "some pretty clear guidelines" that he intends to see through.

Vance will be leading the U.S. delegation in upcoming negotiations, which are slated to begin Saturday morning.

Iran's Deputy Foreign Minister Majid Takht-Ravanchi said Friday that Tehran's proposed 10-point plan will be the basis for the negotiations, according to the Islamic Republic News Agency.

"We do not want a ceasefire that allows the aggressor enemy to rearm and carry out further attacks," Takht-Ravanchi told ambassadors and heads of foreign diplomatic missions.

"The Islamic Republic of Iran always welcomes diplomacy and dialogue, but not a dialogue that is based on false information with the aim of deception and laying the groundwork for another military aggression against Iran," the statement said.

The Islamic Revolutionary Guard Corps (IRGC) said in a statement on Friday that Iran's armed forces have not carried out any airstrikes against other countries since the ceasefire began.

"The Armed Forces of the Islamic Republic of Iran have absolutely not launched any projectiles toward any country during the ceasefire hours up to this moment," the statement said.

The IRGC added that if Iran were to strike any target, it would "courageously announce it in an official statement."

President Donald Trump accused Iran of violating its agreement with the U.S. over the Strait of Hormuz, saying in a social media post on Thursday that it was "doing a poor job" of allowing oil to pass through the waterway.

"Iran is doing a very poor job, dishonorable some would say, of allowing Oil to go through the Strait of Hormuz. That is not the agreement we have!" he wrote.

Trump's post follows another in which he told Iran not to charge fees to oil tankers passing through the strait.
