The United States has attacked three sites in Iran, inserting itself into Israel’s war aimed at destroying the country’s nuclear program in a risky gambit to weaken a longtime foe that prompted fears of a wider regional conflict.

Iranian Foreign Minister Abbas Araghchi warned that any military action by the U.S. in the escalating war with Israel would be "very, very dangerous for everybody."

The US is the only Air Force with the capability to launch so-called “bunker buster” bombing – this enables them to hit targets deep underground.
