President Donald Trump said, in a video posted to Truth Social, "The United States military began major combat operations in Iran. Our objective is to defend the American people by eliminating imminent threats from the Iranian regime, a vicious group of very hard, terrible people.

"Its menacing activities directly endanger the United States, our troops, our bases overseas and our allies throughout the world," he continued.

"For 47 years, the Iranian regime has chanted 'Death to America' and waged an unending campaign of bloodshed and mass murder targeting the United States, our troops, and the innocent people in many, many countries," Trump said.

The US president noted that Iran is the "world's number one state sponsor of terror, and just recently killed tens of thousands of its own citizens on the streets as they protested.

"It has always been the policy of the United States, in particular my administration, that this terrorist regime can never have a nuclear weapon. I'll say it again: they can never have a nuclear weapon."

["...To the members of the Islamic Revolutionary Guard, the armed forces and all of the police, I say tonight that you must lay down your weapons and have complete immunity, or ... face certain death. Finally, to the great, proud people of Iran, I say tonight that the hour of your freedom is at hand! Stay sheltered, don't leave your home, it's very dangerous outside, bombs will be dropping everywhere. When we are finished, take over your government, it will be yours to take. This will be probably your only chance for generations. For many years you've asked for America's help, but you never got it. No president was willing to do what I am willing to do tonight. Now you have a president who is giving you what you want. So let's see how you respond. America is backing you with overwhelming strength and devastating force. Now is the time to seize control of your destiny and unleash the prosperous and glorious future that is close, within your reach. This is the moment for action. Do not let it pass. May God bless the brave men and women of America's Armed Forces, may God bless the United States of America, and may God bless you all." -President Trump via Truth Social] (Screengrab image: via Truth Social)

Trump, on the 10th day of his deadline for Iran, added, "For decades, and decades, they rejected every opportunity to renounce their nuclear ambitions, and we can't take it anymore."

According to Iranian media, explosions were heard in Tehran and other cities, targeting the Ministry of Intelligence, the Ministry of Defense, the office of Supreme Leader Ali Khamenei, and the Atomic Energy Organization of Iran.

The Parchin military complex, located 19 miles southeast of Tehran, was also reportedly attacked. There were also reports in Iran of cyberattacks.

The IDF operation was codenamed "Lion's Roar." June's 12-day operation against the Islamic Republic was named "Rising Lion."

Katz warned that a missile and drone attack targeting Israeli civilian centers was expected "in the immediate future."

He signed an order declaring a special state of emergency across the entire country.

Following a situational assessment, the IDF announced immediate changes to Home Front Command guidelines, moving all areas of the country from Full Activity to Essential Activity.

There is no need to enter shelters, but people should stay near safe rooms, the army said.

Under the guidelines, educational activities, gatherings, and workplaces are prohibited, except in essential sectors.

"You must obey the instructions of the Home Front Command and the authorities and remain close to protected areas," the statement said.

The warning came as sirens blared throughout Israel and alerts were sent to cell phones. Subscribe for free to Breaking Christian News here
