The White House said Wednesday it’s preparing to impose new sanctions on Iran—as early as next week—after President Trump withdrew the U.S. from the landmark 2015 Iran nuclear deal. The move came as President Trump warned Iran of “severe consequences” if it restarts its nuclear program. Iranian President Hassan Rouhani said shortly after Trump’s announcement Tuesday that Iran may start enriching uranium if the multilateral nuclear agreement collapses completely. On Wednesday, Saudi Arabia’s foreign minister, Adel al-Jubeir, told CNN his kingdom is prepared to build its own nuclear weapons if Iran proceeds toward a warhead.

Adel al-Jubeir: “We will do whatever it takes to protect our people. We have made it very clear that if Iran acquires a nuclear capability, we will do everything we can to do the same.”
