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

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."

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.

President Donald Trump issued a warning on social media Thursday while responding to "reports" that Iran is collecting tolls in the Strait of Hormuz, saying "they better not be and, if they are, they better stop now!"

This comes as the president suggested to ABC News Chief Washington Correspondent Jon Karl on Wednesday that the U.S. and Iran could work together to collect tolls.

"We're thinking of doing it as a joint venture. It's a way of securing it -- also securing it from lots of other people," Trump told Karl in a phone call, when asked if he's okay with the Iranians charging a toll for all ships that go through the Strait of Hormuz.
