Israel-Iran updates: Iran launches more missiles at Israel, sirens sound in Tel Aviv and Jerusalem

Israeli Prime Minister Benjamin Netanyahu is planning to speak with President Donald Trump, as well as Russian President Vladimir Putin and U.K. Prime Minister Keir Starmer, later today, according to the Israeli Prime Minister's Office.

The office also said Netanyahu has already spoken to German Chancellor Friedrich Merz, Indian Prime Minister Narendra Modi and French President Emmanuel Macron.

"The leaders expressed understanding for Israel's defense needs against the threat of Iranian annihilation, and the Prime Minister said he will continue to be in constant contact with them in the coming days," according to a statement from the prime minister's office.

There was no time given for when Netanyahu would be speaking to Trump about the strikes.

The U.S. did not play a military role in Israel's attack on Iran as Secretary of State Marco Rubio confirmed, but it provided "exquisite" intel and will help defend Israel if needed -- especially against ballistic missiles that are expected to be launched from Iran, according to a U.S source familiar with the intel on the strike.

The U.S. did have advance notice of the strikes and they will continue and be very intense over the next few days, the source said.

Iran's Natanz enrichment site has been impacted by Israeli attacks, however, there are no elevated radiation levels. The Esfahan and Fordow sites have not been impacted, Iranian officials have confirmed to the International Atomic Energy Agency.

"This development is deeply concerning. I have repeatedly stated that nuclear facilities must never be attacked, regardless of the context or circumstances, as it could harm both people and the environment. Such attacks have serious implications for nuclear safety, security and safeguards, as well as regional and international peace and security," IAEA Director General Rafael Mariano Grossi said in a statement Friday.

"The IAEA has consistently underlined that 'armed attacks on nuclear facilities could result in radioactive releases with grave consequences within and beyond the boundaries of the State which has been attacked,'" Grossi said, citing a general conference resolution.

The IAEA is ready to provide technical assistance and ensure the protection of nuclear facilities, Grossi said.

"IAEA continues to monitor the situation closely, stands ready to provide technical assistance, and remains committed to its nuclear safety, security and safeguards mandate in all circumstances," Grossi said.

Speaker of the House Mike Johnson issued a warning to Iran on Friday, saying it will face grave consequences if it targets U.S. interests.

"Israel and the United States have been united, including in our shared insistence that Iran must never obtain a nuclear weapon. President Trump and his Administration have worked tirelessly to ensure that outcome. Unfortunately, Iran has refused to agree and even declared yesterday its intent to build a new enrichment facility," Johnson said in a statement.

"Israel decided it needed to take action to defend itself. They were clearly within their right to do so," Johnson said.
