Outfront next, breaking news. All eyes on the White House's sources say President Trump

is increasingly considering a strike inside Iran. Is the U.S. about to go to war?

Plus, the bunker buster. See why Israel needs one of America's most powerful bombs a 30,000

pound explosive, to attack Iran's

key nuclear site built inside a mountain. And Iran's firepower. We're learning new details

he wrote, the president may decide he needs to take further action to end Iranian enrichment.

which is why Israel needs this.

America's so-called bunker buster.

The U.S. is the only country that possesses this bomb.
