Sirens sounded in several areas across Israel a short time ago after the Israel Defense Forces said it identified another round of missiles launched by Iran.

Shortly after, the IDF gave the all clear.

The U.S. is moving an additional aircraft carrier to the Middle East, according to U.S. officials, among other U.S. military developments since the start of the conflict between Israel and Iran.

The aircraft carrier USS Nimitz and three destroyers in its strike group are now headed to the Middle East from their current deployment to the Western Pacific, the officials said. The Nimitz is being directed to make its way to the Middle East "without delay," one of the officials said, where it will overlap with the USS Carl Vinson.

In a statement on social media, Defense Secretary Pete Hegseth confirmed that, over the weekend, he "directed the deployment of additional capabilities" to the Middle East. "Protecting U.S. forces is our top priority and these deployments are intended to enhance our defensive posture in the region," he said.

It's possible that additional U.S. Navy ships equipped with missile defense systems will be sent to the Eastern Mediterranean in the coming days and weeks, according to a U.S. official.

The U.S. also moved a large number of midair refueling aircraft to Europe this past weekend as a precautionary move to provide options should the U.S. have to undertake defensive measures, a U.S. official confirmed.

An Iranian state TV news live broadcast was interrupted by Israeli strikes in Tehran on Monday, with smoke and falling debris captured as the news presenter rushed off camera following the sound of a large explosion.

The Israeli defense minister, Israel Katz, confirmed the strikes, which came after the Israel Defense Forces issued a warning to residents in parts of Tehran to evacuate.

"The Iranian regime's propaganda and incitement broadcasting authority was attacked by the IDF after a widespread evacuation of residents in the area," Katz said in a statement. "We have crippled the Iranian dictator everywhere."

It was not immediately clear if anyone was injured in the strikes.

The building was seen on fire following the strike.

The IDF said it targeted the facility based on intelligence that it was "used by military forces to advance operational activity under the cover of civilian assets and infrastructure."

Israeli Prime Minister Benjamin Netanyahu told ABC News on Monday that targeting Iran's Supreme Leader Ali Khamenei would end, not escalate, the ongoing fight between Israel and Iran that erupted late last week.

When asked by ABC News Chief Washington Correspondent Jonathan Karl about reports from ABC News and other outlets that President Donald Trump rejected an Israeli plan to assassinate Iran's supreme leader, concerned that it would escalate the conflict, Netanyahu said, "It's not going to escalate the conflict, it's going to end the conflict."

"We've had half a century of conflict spread by this regime that terrorizes everyone in the Middle East; has bombed the Aramco oil fields in Saudi Arabia; is spreading terrorism and subversion and sabotage everywhere," Netanyahu said. "The 'forever war' is what Iran wants, and they're bringing us to the brink of nuclear war. In fact, what Israel is doing is preventing this, bringing an end to this aggression, and we can only do so by standing up to the forces of evil."
