Saudi Arabia, regional rival of Iran and longtime US ally, said it "supports and welcomes" President Donald Trump's decision to withdraw from the 2015 Iran nuclear deal.
"The kingdom supports and welcomes the steps announced by the US president towards withdrawing from the nuclear deal... and reinstating economic sanctions against Iran," the foreign ministry said yesterday.
Riyadh's allies in the Gulf, the United Arab Emirates and Bahrain, also issued statements via their foreign ministries in support of Trump's decision, which has thrown a wrench between the United States, Europe and their allies in the region.
The US Navy's Fifth Fleet is based in Bahrain, strategically located between Saudi Arabia and Iran.
Trump announced the US withdrawal from the "defective" multinational nuclear deal with Iran yesterday, as Washington moved to reinstate punishing sanctions against the Islamic republic.
After consulting with US "friends" across the Middle East, Trump said his country would "not be held hostage to nuclear blackmail".
