President Trump says US Navy will begin blockade of Strait of Hormuz

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.”

Ukrainian President Volodymyr Zelenskyy confirmed that Ukrainian interceptor drones have been used in "several" countries in the Middle East to destroy Iranian Shahed one-way attack drones.

In a post on X, Zelenskyy said the work carried out in Gulf states by Ukrainian interceptor drone and electronic warfare teams was "about building a modern air defense system that can actually work."

The Ukrainian leader said his country was able to share its own experience in anti-drone defense to "quickly advise" on how to make air defense systems stronger.

Zelenskyy also noted that faster-type Iranian drones which are powered by jet engines were also intercepted and said it was only a matter of time "before we begin mass production of interceptors that will destroy drones with jet engines."
