Trump said the U.S. attacked three nuclear sites in Iran.
The United States struck three nuclear sites in Iran on Saturday, President Donald Trump announced.
B-2 bombers dropped a number of Massive Ordnance Penetrator bombs -- known as "bunker busters" -- during the U.S. mission over Iran, a U.S. official confirmed.
A number of Tomahawk cruise missiles were also fired at targets inside Iran from a U.S. Navy submarine, the official confirmed.
Following the strikes, Trump addressed the nation, calling it a "spectacular military success."
Israeli forces launched a series of strikes in western Iran Tuesday, the Israel Defense Forces said in a statement.
Israeli forces have also conducted "intelligence-based strikes on surface-to-air launch sites and radars embedded in western Iran," the IDF added.

Iran is not currently building a nuclear weapon, a senior Trump administration official told ABC News.
"Just because they’re not building right now, doesn’t mean they aren’t 'very close' as POTUS said on Air Force One," the official said on Tuesday.
"All of the other points [U.S. Director of National Intelligence Tulsi Gabbard] made outside of the singular statement that 'Iran is not building' a nuclear weapon, points to them being very close to building one," the official said.
In March, Gabbard testified to congress that the intelligence community "continues to assess that Iran is not building a nuclear weapon and Supreme Leader Khamanei has not authorized the nuclear weapons program he suspended in 2003."
"Iran's enriched uranium stockpile is at its highest levels and is unprecedented for a state without nuclear weapons,” Gabbard added.
"Iran continues to seek expansion of its influence in the Middle East, despite the degradation to its proxies and defenses during the Gaza conflict. Iran has developed and maintains ballistic missiles, cruise missiles, and UAVs, including systems capable of striking U.S. targets and allies in the region," Gabbard said.
An International Atomic Energy Agency report in June concluded that it had "no credible indications of an ongoing, undeclared structured nuclear programme."
Satellite images of Iran’s main nuclear facility show "direct impacts on the underground enrichment halls at Natanz," Iran's main nuclear facility, according to the International Atomic Energy Agency.
On Monday, there was no indication of a strike on the underground portion of the facility, including the main fuel enrichment plant, but there were strikes on above ground buildings including the facility’s power supply, according to IAEA Director-General Rafael Grossi.
Israeli Defense Minister Israel Katz on Tuesday warned Iran’s Ayatollah Ali Khamenei that his fate could be similar to that of former Iraqi leader Saddam Hussein if his forces continue to target Israel.
“I warn the Iranian dictator against continuing to commit war crimes and fire missiles at Israeli citizens,” Katz said. “He should remember what happened to the dictator in the country neighboring Iran who took this path against the State of Israel.”
Hussein was toppled by the U.S. invasion of Iraq in 2003. After nine months on the run, he was captured near the city of Tikrit. An Iraqi tribunal convicted Hussein of crimes against humanity and executed him by hanging in 2006.
Katz also said Iran’s “replacement chief of staff,” was killed in Israeli strikes on Iran overnight.
