Iran live updates: IRGC says Strait of Hormuz will 'never' revert to pre-war state

French President Emmanuel Macron expressed concern over the war in Iran and suggested that the U.S. is starting to "jeopardize" the world order that it helped build after World War II, he said Friday, while speaking to students at Yonsei University in South Korea.

"Iran is a very bad regime - no discussion about that. I disagree with them on a lot of topics. But I don't believe that we will fix the situation just by bombings or by military operations. Look at what happened with this type of operation in Iraq, in Afghanistan, in Libya - we never delivered. Never. Even after 20 years," Macron said.

"So you have to respect the sovereignty of people. If people want to change a regime, they want to react, step up, they can do so," he said.

An American fighter jet appears to have been shot down by Iran, according to a U.S. official. Search and rescue operations are currently underway, the official said.

Israel and the United States will "continue to crush" Iran, Israeli Prime Minister Benjamin Netanyahu said Friday during remarks at a military facility in Tel Aviv.

"Together with our American friends, we continue to crush the terrorist regime in Iran. We are eliminating commanders, bombing bridges, bombing infrastructure," Netanyahu said.

"In full coordination between me and President [Donald]Trump, between the IDF and the United States military, we will continue to crush Iran. This regime is weaker than ever - Israel is stronger than ever," Netanyahu added.

At least eight civilians were killed and 95 others were injured in the U.S.-Israeli attack on the B1 bridge between Karaj and Tehran on Thursday, according to Iran's semiofficial Fars News Agency, which is affiliated with the Islamic Revolutionary Guard Corps.

ABC News can not independently confirm the deaths.
