Trump says damage to Iran's nuclear sites is 'far below ground level'

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."

The State Department on Monday upgraded its Israel, West Bank and Gaza travel advisory to a Level 4 "do not travel" warning.

The warning comes shortly after the State Department authorized the voluntary departure of family members and nonemergency U.S. government employees "due to the volatile and unpredictable security situation in the region," the alert said.

The death toll in Israel from Sunday night's Iranian ballistic missile strikes rose to eight people as of Monday, authorities said, as recovery efforts at impact sites continue.

At least 24 people have now been killed in Israel since the country launched its surprise attack on Iran on Friday, according to the latest figures released by Prime Minister Benjamin Netanyahu's office on Monday.
