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."
Sirens sounded in several areas of Israel following the military's identification of incoming missiles, the Israel Defense Forces said in a release.
It is now clear, and people in Israel have been allowed to leave shelters, according to the IDF.
The time between the incoming announcement and the announcement to leave shelter was about 20 minutes.

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.
