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."
Rep. Jim Himes, the ranking member of the House Intelligence Committee, was only notified of the strikes after they had occurred, a source familiar told ABC News.
There was not a formal Gang of Eight briefing, the source added.
